Description: Most facilities and design engineers of industrial control panels assume a higher risk for voltages 50V and below and often think electrical safety is only critical when system voltages are greater than or equal to 100 Volts. This leads to a mindset where everyone is heavily focused on risk mitigation tactics when safety-by-design controls are applied only to voltages of higher magnitude, leaving the control systems behind.
Further, automation engineers and control system experts in manufacturing and process environments often work with control panels for process optimization while interacting heavily with low voltage components such as PLCs and other control devices inside the panels. This webinar will draw importance to unintentional exposure of electrical safety risks to design and control engineers while working primarily with low voltage devices inside the industrial control panel.

Learning objectives: 
• Electrical exposures and hazards involved in Industrial control panels and machinery
• NFPA 79 & 70E guidance on safety requirement
• Best practices for industrial control panel design
• Risk mitigation and productivity enhancements using thru-door programming ports

Speakers: John Kolak, CSP & Bhanu Srilla, Director of Product Marketing

All registrants will receive a follow-up email after the presentation with a link to an on-demand video version of the webinar as well as downloadable slides. We hope to see you there!

Features: Scope, V-A-HZ, Monitor, Trend, Events, ground

Problem Description

Ever fixed something and still not solved the problem? Sometimes multiple deficiencies can all cause the same symptoms.

In this case, an industrial facility was having communication problems with a network hub. During the initial survey data gathering phase, they documented equipment failures and port problems all the way back to the hub equipment installation.

After the service company exhausted all hardware and software options, they called in a consultant to find out whether it was a power quality problem. Using his handheld Fluke 434 three-phase Power Quality Analyzer, the consultant found more than expected.


After connecting his Fluke 434 to the branch circuit supplying the hub equipment, he checked the View Config screen (Fig. 1) diagram to verify proper connections. From there, he pushed the Scope button and saw an abnormally high neutral waveform. (Fig. 2) He checked the numeric values at the top of the screen and saw that neutral voltage was in fact incredibly high, at 23 volts, indicating a possible neutral-ground issue. He saved that screen for customer documentation.

Just to be sure, he switched to the V-A-Hz screen (Fig. 3) and checked the voltage level again. He got the same results. Following standard power quality practices, he began looking for a grounding problem at the branch circuit, since that was the next step in the wiring path.

He traced the branch circuit to the isolated ground receptacle but couldn't find a grounding conductor. That was a little too isolated! Not having a grounding conductor caused an open ground condition. That was not only a problem for the electronic equipment, but also a safety hazard to personnel and equipment. As a temporary fix, he recommended replacing the isolated ground receptacle with a legal, standard receptacle. The standard receptacle would allow the client to use conduit as the standard equipment grounding providing proper grounding for the branch circuit.

During his examination of the branch circuit, the consultant also discovered that the circuit was supplied from a general-purpose electrical panel. Since he knew the hub would require higher quality power than average equipment, he thought he should go ahead and check the panel for any kinds of sags or swells.

He pressed the Monitor button (Fig. 4) and set the recording time for 24 hours. After the first 15 minutes, he pushed the trend button while continuing to record in the background. (Fig. 5) Shortly into the cycle he saw a dip in the line.

To learn more, he pushed the event table button, checked the numeric values, and saw distinct voltage sags on the branch circuit. (Fig. 6)

The panel was clearly carrying too much load, most likely from one or more of the facility's large motors. That meant the hub was seeing high voltage from the grounding problem and low voltage from the sags, both of which were causing the hub to go down.


Due to the cost and time required to install a new receptacle on the branch circuit, the facility decided to add a UPS in front of the power supply to the hub. Since the remaining equipment on that line wasn't disrupted by the sags, no further actions were required. The consultant downloaded a report of the benchmark power quality measurements he'd made and gave it to the facility, who agreed to set up a regular preventive maintenance schedule.

<![CDATA[Grounding and Bonding Tips for Electric Signs, Isolated Equipment and Cabling [Advice from Electrical Engineering Experts]]]> https://www.colterlec.com.au/news/postgrounding-and-bonding-tips-for-electric-signs-isolated-equipment-and-cabling-advice-from-electrical-engineering-experts https://www.colterlec.com.au/news/postgrounding-and-bonding-tips-for-electric-signs-isolated-equipment-and-cabling-advice-from-electrical-engineering-experts Fri, 11 Jan 2019 00:00:00 GMT When it comes it to electrical safety, grounding and bonding are integral. Across various industries, applications and facility types, grounding and bonding requirements may be different.

In this edition of electrical engineering news and information, we overview how to ground and bond in the following situations:

  • Electric signs and outline lighting
  • Cabling in industrial factories and other facilities integrated with the Internet of Things (IoT)
  • High-end media centers (or any isolated environment)

How to Ground and Bond Electric Signs and Outline Lighting

Safe grounding for outline lighting, electric signs or skeleton lighting entails more than simply connecting the green power ground to the appropriate terminal. An article from EC&M iterates that it requires bonding all metal equipment from these systems to the equipment grounding conductor (EGC).

Article 250 of the 2017 National Electrical Code (NEC) covers EGC requirements:

  • To specify the EGC type to use, refer to section 250.118.
  • Once the rating of the overcurrent device protecting the circuit conductors supplying the system has been determined, section 250.122 provides the size.
  • Make the EGC connection according to section 250.130, using one of the methods specified in 250.8. 

For more details on how the NEC specifies grounding and bonding for outline lighting and electric signs, read the full article on EC&M.

The Misunderstood Concept of Isolated Grounding

The author of this article, Mark C. Ode, provided a homeowner with the playbook for effectively grounding the high-end media room after he had received conflicting advice.

The audio company engineer had instructed the homeowner to install a “2/0 welding cable from the isolated equipment ground bar in the media room panel to two separated ground rods” located outside of the building. This 1980’s concept had once been proposed in order to isolate high-frequency sensitive equipment from the normal grounding system. But, by creating an isolated ground without a path for fault current to return back to the source, it will not fully clear a fault in one of the circuits by tripping a breaker or blowing a fuse.

In 1990, NEC 250-21 (d) clarified this incorrect assumption by stating “the provisions of this section shall not be considered as permitting electronic equipment being operated on AC systems or branch circuits that are not grounded as required by this Article. Currents that introduce noise or data errors in electronic equipment shall not be considered the objectionable currents addressed in this section.” 

This means that entirely isolating the equipment grounding conductors from the electrical system using two separate ground rods has never been acceptable. To discover what ultimately was recommended and to read a more comprehensive overview of the situation, check out Electrical Contractor.

Grounding and Bonding Requirements for Cabling

IoT emergence means cabling systems are being installed where they were not in previous years. An interview conducted by Cabling Installation & Maintenance with Sam Rodriguez, a senior product manager at a cabinet and thermal-management solution provider, helps define grounding and bonding requirements for cabling in these environments.

When asked about the difference between cabling deployments in data centers compared to other environments, Rodriguez emphasized the control variances. Very few people have access to data centers, while cabinets in industrial environments are at a greater risk to accidents due to activity and related problems (e.g. water or puddling). 

Additionally, grounding system planning is an inherent and integral piece of the data center planning. The same is not always true for other enclosures.

Enclosures can be considered “IT” enclosures or “industrial” enclosures. IT enclosures will typically come with a grounding kit, but industrial enclosures often do not. This increases the knowledge and education an industrial purchaser and installer will need to ensure correct grounding requirements are met. 

As cabling becomes more widely deployed in new environments, new electrical risks emerge. Read the full article on the Cabling Installation & Maintenance to learn more.

<![CDATA[Reducing motor drive troubleshooting complexity with the Fluke MDA-550 Motor Drive Analyzer]]> https://www.colterlec.com.au/news/postreducing-motor-drive-troubleshooting-complexity-with-the-fluke-mda-550-motor-drive-analyzer https://www.colterlec.com.au/news/postreducing-motor-drive-troubleshooting-complexity-with-the-fluke-mda-550-motor-drive-analyzer Tue, 18 Dec 2018 00:00:00 GMT Motor drives. They're everywhere and essential to adapting the speed of a motor to the needs of an application. Also called variable speed drives (VSD), variable frequency drives (VFD) and adjustable speed drives (ASD), motor drives are an important behind-the-scenes component in fans, pumps, compressors and other motor-driven equipment.

Danfoss, a global maker of commercial refrigeration and heating systems, hydraulics and motor drives is one of the largest industrial companies and employers in Denmark. Founded by legendary innovator Mads Clausen, the 50-year old company has installed millions of motor drives around the globe. Danfoss recently partnered with Fluke to test the new Fluke MDA-550 Motor Drive Analyzer.

Norbert Hanigovszki, Project Director in the Technology Development Group of the Danfoss Drives division is often required to help with his expertise troubleshooting and supporting motor drive applications in the field. He has been with the company for 16 years and holds a bachelor's and master's degree in electrical engineering, as well as a doctorate in EMC and power electronics.

"Today, when you go to a site for a service call and you don’t know exactly where you want to start looking or what you want to investigate, you will probably take with you a multimeter, an oscilloscope and a power analyzer," said Hanigovszki. "Besides that, you will need to have some special knowledge you have gained through experiences."

Carry less and do more with the Fluke MDA-550 Motor Drive Analyzer

"The motor drive analyzer changes things because you will only need one instrument," says Hanigovszki. "It's good enough for in-depth troubleshooting, and another advantage is that you get help from the instrument, from the diagrams and instructions."

"It's sort of like a wizard. It tells you what you want to measure. If you want to measure, for example, the voltage of the output of the drive, it will pre-set the instrument in order to measure that particular spot."

The MDA-550 includes walkthroughs for all essential tests including drive input, DC bus - ripple, drive output, motor input and motor shaft voltage. Once a technician chooses a test:

  • Voltage and current visuals appear and prompts provide step-by-step guidance to ease the process of connecting to a variable frequency drive
  • Preset measurement profiles collect data based on the chosen test procedure and reduce the need to perform complex configurations
  • Built-in report writing allows all technicians to produce professional as-found and as-left motor-drive troubleshooting reports

What's the "killer application?"

Making motor shaft voltage measurements with the MDA-550Checking motor shaft voltage with the Fluke MDA-550

Hanigovszki said all motor drive analysis tests are important, however for him the "killer application" in the Fluke MDA is the motor shaft voltage testing function which can check for electrical discharge in motor bearings.

"To troubleshoot, you need to analyze the discharge in the bearing from both a qualitative and a quantitative point of view," said Hanigovszki. "That means you want to see how big this discharge is, because the bigger the discharge the more damage it can produce. But you also want to know how often the discharge occurs because, clearly, the more often it occurs, the more damage or the faster the bearings will wear out."

Measuring a fast turning motor shaft can be troublesome and risky. The MDA-550's shaft voltage probe provides a safe and easy way to make electrical connections to motor shafts by using a small conductive brush. This test, unique to the MDA-550 includes a preset test routine direct from the menu and shows exactly how to ground and connect to the voltage and current

"The uniqueness of the motor drive analyzer is that it enables both a qualitative and a quantitative analysis so you will both—know how many discharges you get, and you will know the amplitude of the discharge and, like on any oscilloscope, you will be able to see the waveform to then quickly troubleshoot motor bearing problems."

Importance of harmonics analysis

Hanigovszki emphasizes that not only will you want to look at what is happening the outside of the drive toward the motor, you will want to look at the grid side of the drive—how the drive impacts the supply grid.

At the input of the drive, the motor drive analyzer can perform harmonic analysis. Motor drives can produce harmonic distortions that can potentially cause problems on other electrical equipment.

"Thus, with the MDA 550 you have a tool that will give you an indication if you are overloading the grid with harmonics and harmonics are a secondary effect of power electronics in general," he said, "because power electronics tend to draw non-sinusoidal current from the mains and the analyzer can be used to assess the impact on the grid."

Easily generate reports

The Fluke MDA-550 also lets you easily gather data and create test reports with a built-in report generator, as well as store and replay up to 100 of your most recent screens.

"Because when you are in the field and you see something and it's just a short glitch and then it's gone, you often are in this situation where you say ‘I wish I had saved that or I had captured that,' " said Hanigovszki. "But with this instrument it's very easy. You just hit replay and you rewind to the time where you observed whatever was interesting for the investigation."

When discussing the technicians who would use this instrument, Hanigovszki notes that they don't have to be drive specialists because of the wizards and diagrams available to help them correctly measure motor drives.

"The instrument is already set to perform the measurement," he says, "so the time scale will also be correct for the selected type of measurement. That is helpful for the non-motor drive specialists."

Do you want to learn more?

Fill out our short Demo Request form and we will contact you to schedule your personal demo from a qualified Fluke engineer. You'll get a hands-on demonstration of the instrument in your workplace, focused on the measurements you need. You'll see how easy our instruments are to use, and receive training and advice on both the instrument and related accessories. So, if you buy, you're sure to select the instrument that's right for you, and get the most out of it!

<![CDATA[Danfoss New 8.5 TR and 11 TR variable speed compressors with IDV]]> https://www.colterlec.com.au/news/postdanfoss-new-85-tr-and-11-tr-variable-speed-compressors-with-idv https://www.colterlec.com.au/news/postdanfoss-new-85-tr-and-11-tr-variable-speed-compressors-with-idv Tue, 18 Dec 2018 00:00:00 GMT Danfoss has added new 8.5 TR and 11 TR (*) variable speed compressors with IDV(**) to its popular VZH range, giving commercial cooling manufacturers the market's most complete choice of variable speed scrolls with qualified drives for HVAC systems.

In particular, the new inverter scrolls are ideal for data center close control units, where they will enable precise and efficient cooling.

They're also an excellent fit for rooftop units, helping manufacturers to meet challenging new seasonal and part-load efficiency standards (IEER), like the US Department of Energy's energy conservation regulations coming into force in 2023. Likewise, for chillers, the Danfoss VZH range will enable OEMs to develop a competitive range of systems capable to exceed the demanding Ecodesign Lot 21 targets coming into force by 2021.



Luigi Zamana, Senior Marketing Director for Danfoss Commercial Compressors, says: "The extended VZH range also gives OEMs the opportunity to work with a single, proven supplier of pre-qualified variable speed compressor and drive packages, from 4 TR up to 26 TR, with scroll technology and from 60 TR to 400 TR with oil-free Turbocor technology.

Thanks to Danfoss, there are today more options for energy efficient solutions, precise cooling and superior comfort. Danfoss enables real design strategies with the various compressor technologies in our offering, keeping in mind the total system life cycle cost".

(*) @ ARI conditions, full speed (110 RPS)

(**): Intermediate Discharge Valve for improved part-load efficiency

Variable speed with IDVs: the key to SEER, IPLV and IEER

Worldwide, energy efficiency standards are increasingly based upon seasonal efficiency measures like the Seasonal Energy Efficiency Ratio (SEER), Integrated Energy Efficiency Ratio (IEER), and Integrated Part Load Value (IPLV). These standards are designed to better reflect the actual average and yearly load profile.

Cooling manufacturers are therefore under pressure to improve part-load efficiency in order to satisfy US-DoE, Chinese IPLV and APF and EU Ecodesign regulations, and continue to sell units in major world markets.

With their ability to continuously modulate capacity, variable speed compressors are acknowledged as a key part of meeting this challenge.

However, Danfoss VZH scrolls go further. They feature Intermediate Discharge Valves (IDVs), which prevent the over-compression losses that compromise efficiency in standard scroll technology under part-load conditions. The result is a significant improvement in integrated efficiency scores. Efficiency is further improved by the VZH range with the use of the latest permanent magnet motor technology that helps reducing power consumption at all operating conditions.

Tailor-made for rooftop units, and IT close controls

Energy efficiency is particularly important in data center cooling applications. With round-the-clock cooling demand, throughout the year, each incremental reduction in power consumption has a disproportionately large impact on energy bills – giving IDVs a clear role to play in making data centers more sustainable. IDVs will indeed deliver much higher system efficiency for the same cooling capacity especially at very high evaporating temperatures (low pressure ratios), that are typical of the data center functioning.

But servers also need precise conditions to function reliably, and the variable speed technology gives an unparalleled ability to achieve a narrow, 0.3 °C temperature window, without sacrificing Power Usage Effectiveness (PUE).

This, and the VZH extended operating map and compressors' ability to work in a wide range of conditions, makes them an obvious choice for IT close control systems – as well as rooftop units in markets where seasonal efficiency is a priority.

Pre-qualified packages accelerate time to market

Importantly, Danfoss is able to supply right-sized compressors and drives as a matched, pre-qualified and certified package.

This dramatically accelerates the development process, so OEMs who are racing to satisfy new environmental standards will be able to bring new, more efficient units to market faster.

Luigi Zamana continues: "Since the beginning, we have earned a strong reputation for prequalified compressors and drives packages. We know our OEM customers appreciate it when we combine this know-how, to make their development process faster, easier and more reliable, so we're pleased to offer a perfectly matched package."

F-Gas compliant – with a roadmap to even lower GWP

Currently, VZH compressors are approved for use with R410A – one of the most popular refrigerants for HVAC and data center applications.

With a Global Warming Potential (GWP) of less than 2500, R410A is unaffected by the F-Gas phase down in the short term. Meanwhile, Danfoss's commitment to lower-GWP alternatives – including its new, 3000 m2 testing facility for flammable refrigerants – means the company has spelled out a clear road map for a safe, managed transition before phasedown commences in earnest.

Luigi Zamana adds: "At Danfoss, we're helping HVAC engineers to solve their biggest environmental challenges– seasonal energy efficiency, and F-Gas – with sustainable, cost-efficient technology and refrigerant options.

"We were the pioneer of oil-free compressors, and variable speed inverter scroll technology, so we have the experience, support and proven reliability to help manufacturers give specifiers and engineers the dependable, efficient performance they expect."

<![CDATA[nVent Erico A Year in Review: 6 Top Electrical Engineering Posts from 2018]]> https://www.colterlec.com.au/news/postnvent-erico-a-year-in-review-6-top-electrical-engineering-posts-from-2018 https://www.colterlec.com.au/news/postnvent-erico-a-year-in-review-6-top-electrical-engineering-posts-from-2018 Tue, 18 Dec 2018 00:00:00 GMT During this long year, the nVent ERICO team of engineering and product experts has published dozens of posts focusing on electrical safety, grounding, bonding and more. Before surging ahead into 2019, see which six posts were viewed the most this year.

Looking for another recap post? Check out top electrical engineering posts from 2017.

1. The Benefits of Copper-Bonded Ground Rods

As the final piece needed to ground an electrical current, ground rods are imperative for grounding system performance. In most applications, the nVent ERICO team recommends copper-bonded ground rods because they:

  1. Have a strong core, increasing the likelihood of a long, dependable service life.
  2. Are less susceptible to corrosion than other materials in most environments.
  3. Increase cost efficiency over the service life of the rod. 

See the full post to learn more about these three key reasons engineers should choose copper-bonded ground rods over other materials.

2. How Does Lightning (and a Lightning Protection System) Work?

Across the U.S., lightning strikes an average of 25 million times per year and occurs at a rate of 100 flashes per second worldwide. And while the location of each strike is unpredictable, facilities can be better protected against this devastating phenomenon with a lightning protection system. 

Many different national and international standards cover the manufacturing and installation of lightning protection systems, but there are two consistent aspects that determine the performance of the lightning interception: Physical hardware and hardware positioning. 

Read The Science of a Lightning Strike and How to Safeguard Your Facility with a Lightning Protection System for more information.

3. What’s What: Grounding, Bonding and Earthing

These three electrical terms have confused people for years. As integral parts of modern electrical protection systems, understanding the differences is important. 

  • Ground: A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth.
  • Earth: The conductive mass of the earth, whose electric potential at any point is conventionally taken as equal to zero. In some countries the term "ground" is used instead of "earth."
  • Bond: The permanent joining of metallic parts to form an electrically conductive path that will ensure electrical continuity and the capacity to conduct any current likely to be imposed. 

Find out the benefits of grounding, the relevant codes and standards and the principles of grounding by viewing What’s What: Grounding, Bonding and Earthing.

4. What Is the Difference Between Copper-Clad and Copper-Bonded Steel? 

A common misconception is that copper-clad and copper-bonded steel are the same. In actuality, the only significant similarity is that both consist of a steel core and copper exterior. In copper-bonded steel, the bond is made permanent at the molecular level between the two materials. Copper-clad, however, is pressure heated to connect the two metals. 

In practice, copper-bonded steel is used in manufacturing ground rods, solid wire and solid conductors. Copper-clad steel, because the bond is not nearly as strong, is not used for grounding rods today. 

For a more detailed explanation of the differences, see What Is the Difference Between Copper-Clad and Copper-Bonded Steel?

5. The Risks of Lightning: For Beginners

Dating back to the 1700s, Benjamin Franklin was one of the first to study and document the dangers and effects of lightning. Though we still cannot predict where lightning will strike next, the knowledge gained about lightning risks and basic lightning protection systems has grown drastically over time. 

Step potential, touch potential and side flashing are all lightning-related risks. And to help safeguard facilities, personnel and electronic devices from all of those risks, a lightning protection system must do the following:

  • Intercept lightning flashes
  • Conduct the lightning current to the earth
  • Dissipate the current to the earth
  • Create an equipotential bond to prevent potential differences between the system, structure and internal circuits

Delve deeper into this topic by reading the beginner’s guide to lightning risks and protection methods.

6. What is Facility Electrical Protection?

Facility electrical protection is the nVent ERICO engineered systems approach to protecting property from lightning damage and other electrical transient events. By providing innovative, interconnected lightning, grounding and bonding and surge protection systems, facilities can become better equipped to handle dangerous and costly electrical events.

Read the full post on facility electrical protection to discover how each of these systems works individually and with the other systems to increase safety and reliability for facilities.

Stay Current in 2019

After an eventful 2018 for the nVent ERICO team, 2019 will be packed with even more electrical engineering information, advice and news. Subscribe to our blog to stay up-to-date on every post.

<![CDATA[Busy elevator electronics technician saves time with new Fluke motor drive analyzer]]> https://www.colterlec.com.au/news/postbusy-elevator-electronics-technician-saves-time-with-new-fluke-motor-drive-analyzer https://www.colterlec.com.au/news/postbusy-elevator-electronics-technician-saves-time-with-new-fluke-motor-drive-analyzer Wed, 31 Oct 2018 00:00:00 GMT

The company employs scores of general purpose technicians on its maintenance team to perform preventative maintenance, troubleshoot and repair malfunctions, and even do post-mortems after failures to learn how they might be prevented in the future. In addition to the generalists, there is a group of five electronic specialists who cover the entire area. They primarily troubleshoot the increasingly sophisticated control systems, load weight devices and variable speed drives used to keep the elevators running smoothly.

Ups and downs of elevator maintenance

Motor drives in elevators are also called variable frequency drives (VFD), frequency converters or adjustable speed drives (ASD). They transform constant voltage from the main ac power supply into a voltage that varies to control motor torque and speed, ideal for motors that drive the cable or belt systems that move the elevators up and down.

One veteran electronics technician at the elevator company said he has typically used Fluke ScopeMeter® Test Tools (125B and 190) to troubleshoot drives. Recently, however, he switched to the new Fluke MDA-550 Motor Drive Analyzer. The technician is highly skilled with 25 years of experience, including electronics and telecommunications in the military and a degree from a technical school.

The new motor drive analyzer, he said, is great for both very skilled or less skilled technicians.

"It's a nice tool for everyone because you have guidance. And the interface takes you through the process of measuring," the elevator electronics technician said.

Troubleshooting made easy

The MDA combines a handheld oscilloscope with a multimeter and adds easy-to-read diagrams and step-by-step guidance through tests.

“The good thing about the MDA is that, for a skilled technician, you have the pictograms that show you how to set up the tool. That saves time on each testing,” he said. “The lower skilled technician can confirm the setup before they begin and move through the test, step by step.”

The MDA includes a walkthrough for all key tests, including:

  • Drive input
  • DC bus­­—ripple
  • Drive output
  • Motor input
  • Motor shaft voltage

“The MDA has all of these functions. It’s a great upgrade. For me it’s about simplifying my work. I can do all the same measurements that I can with the scopemeter, but it’s easier to use. You just pick the test and the settings are all ready to go.”

Fluke motor drive analyzers guide you through these tests and automate many of the needed calculations so you can have confidence in the results. Plus, you can save data to a report at nearly any test point, so you can have documentation to upload to a computerized maintenance management system (CMMS) or share with a colleague or consulting expert.

“I could do it with the oscilloscope using manual settings, but the MDA test is all set up and ready to use. When you’re doing a lot of measurements in one day, that saves a lot of time.”


Confirming suspicions and fixing problems

In one recent service call, the electronics technician was troubleshooting a large elevator at a hospital. “Because of 14 years of work, the motor drive showed ripple on the load. They were ripples of the DC link. We thought it might have something to do with the aging of the capacitors. They tend to get drier and drier as they age.

“That’s a problem—the elevator will need more and more current because the capacitors will need more and more current. The result is that the capacitors get weaker and weaker, and you waste energy.

Using the MDA, I was able to go to the DC bus test and the DC ripple and quickly complete the test and confirm what we suspected,” he said.

They ended up changing out the whole bank of capacitors to fix the problem.

“I could do it with the oscilloscope using manual settings, but the MDA test is all set up and ready to use. When you’re doing a lot of measurements in one day, that saves a lot of time.”

<![CDATA[New Danfoss solution further improves the efficiency of CO₂ refrigeration in all climates]]> https://www.colterlec.com.au/news/postnew-danfoss-solution-further-improves-the-efficiency-of-co-refrigeration-in-all-climates https://www.colterlec.com.au/news/postnew-danfoss-solution-further-improves-the-efficiency-of-co-refrigeration-in-all-climates Wed, 31 Oct 2018 00:00:00 GMT The new CO₂ Adaptive Liquid Management (CALM) solution allows full utilization of the evaporator surface in display cases and cold rooms, improving energy savings with CO₂ refrigeration in any store. CALM is a complete solution; in addition to intelligent pack and case controllers and a system manager, it includes two ground-breaking Danfoss innovations: The Liquid Ejector and the Adaptive Liquid Control case controller algorithm.

New liquid ejector completes the Danfoss multi ejector solution™ portfolio

With CALM, Danfoss introduces the new Liquid Ejector which can optimize and improve any transcritical CO₂ booster or parallel compression refrigeration system. Like existing Danfoss ejector offerings, the Liquid Ejector is driven by expansion energy from the gas cooler but uses it to remove liquid from the suction side. As it requires little energy to run, the Liquid Ejector is efficient in all ambient temperatures, providing a truly global optimal solution for any climate. 

"The new Liquid Ejector strengthens the Danfoss ejector portfolio," comments Danfoss Product Manager Przemyslaw Kalinski. "We now offer an ejector solution for all climates, CO₂ system types, and system sizes. In short: an efficient CO₂ refrigeration solution for everyone."

Adaptive Liquid Control algorithm optimizes evaporator control 

As the Liquid Ejector protects compressors by removing liquid from the suction side, the new Adaptive Liquid Control (ALC) case controller algorithm can safely increase evaporator utilization by injecting more refrigerant, thereby increasing the evaporation temperature and controlling superheat close to zero. As a result, evaporator performance is optimized, the suction pressure is increased, and the compressors consume less energy. 

"While an adaptive Minimum Stable Superheat algorithm is the most efficient and robust solution for injection control with dry expansion, Adaptive Liquid Control is the most efficient and robust algorithm for liquid control, for example in transcritical CO₂ systems," says Danfoss Product Manager Ejnar Luckmann. 

CALM provides significant energy savings and cost reductions 

Increasing the evaporation temperature makes it possible to save significant amounts of energy because the increased suction pressure reduces the load on the compressors. In fact, the Adaptive Liquid Control algorithm can achieve energy savings of typically 5% compared to Minimum Stable Superheat solutions and twice as much when compared to solutions with fixed superheat. 

The CALM solution further ensures a reduction of first-cost investments. As an example, a smaller suction accumulator will be sufficient to handle the limited amount of liquid in the suction line. There will also be a reduction of compressor capacity need and therefore, there is the possibility of installing smaller or fewer compressors. 

"We Love CO₂": Danfoss working to make the refrigerant transition happen 

As refrigerant legislation tightens, and the consequences of climate change are becoming increasingly clear, the transition to climate-friendly refrigerants is a top priority. Thousands of CO₂ refrigeration installations prove that Danfoss components can help customers make this transition whilst saving energy, and without compromising on food safety and reliability. With the CALM solution, Danfoss now offers an even greater selection of CO₂ solutions for all climate zones and store sizes, helping businesses make the refrigerant transition all over the world. 

"These benefits are now available to end-users all over the world and it’s a major step forward in developing solutions that benefit the climate. We are proud to say that "We love CO₂", and we hope that decision-makers in the food retail industry will join us in making the refrigerant transition happen," says Anja Sofie Meiner Jensen, Project Launch Manager.

<![CDATA[The 2 Most Important Factors to Weigh When Selecting Ground Rod Material by eVent Erico]]> https://www.colterlec.com.au/news/postthe-2-most-important-factors-to-weigh-when-selecting-ground-rod-material-by-event-erico https://www.colterlec.com.au/news/postthe-2-most-important-factors-to-weigh-when-selecting-ground-rod-material-by-event-erico Wed, 31 Oct 2018 00:00:00 GMT Factors to Consider in Grounding System Design

Consider the relationship between expected service life and cost in order to receive the best value from your ground rod. Below, we uncover the top two most important factors to consider before selecting a ground rod material.

1) Corrosion Resistance and Longevity

The expected service life should be the first— and most important— factor considered when selecting ground rods for a grounding system.

A ground rod’s resistance to corrosion is directly related to service life and overall system effectiveness— the quicker a ground rod corrodesthe shorter the service life and overall cost will be. Because below-grade products are exposed to significant corrosion threats, the service life between two materials can vary by years or decades. The resistance of a ground rod will significantlyincrease when corroded and can result in a catastrophic loss of ground over time.

2) Cost

Cost generally comes into play when contractors are attempting to cut costs by using a cheaper material, or balancing cost and corrosion resistance between materials like solid copper and stainless steel. When a grounding rod specification does not reference a specific brand, product or material, a contractor may choose the cheapest allowable ground rod. However, to maximize value and produce the safest, most reliable system for users, that may not be enough.

The upfront cost of one ground rod material should not be compared directly to another material. Rather, the lifecycle value of two materials should be compared. If one rod is $20 and another costs $30, but the cheaper rod will only last one-quarter as long as the other, the more expensive rod is clearly the more cost-effective choice.

National Electrical Grounding Research Project

To appropriately balance service life and cost when comparing ground rod materials, we can point to established studies from reputable third-party organizations for proof.

In 1996, the Fire Protection Research Foundation established the National Electrical Grounding Research Project (NEGRP), which studied the long-term performance of 18 different grounding electrodes in diverse geographical locations and soil types. It is the most extensive study on corrosion involving copper and galvanized material since a National Bureau of Standards study from 1910-1955.

Comparing the Service Life and Cost of Common Ground Rod Materials

Common ground rod material selection is based on the corrosion resistance of the rod, balanced with the longevity of the system. Galvanized steel, copper-bonded steel and stainless steel are the most common materials considered for grounding systems in most parts of the world.

Galvanized steel rods are often the go-to material because they are cheap, allowed by the NEC and UL listed. However, in the NEGRP study referenced above, it’s been uncovered that galvanized rods are an inferior material choice in terms of service life longevity. Also note that choosing a material based solely on its upfront cost does a disservice to the grounding system’s users and their safety, and will likely cost more in the long term.

Copper-bonded ground rods are a major step up in terms of corrosion resistance. The NEGRP found that copper-bonded ground rods last an average of 40 years in most soil types, compared to 15 for galvanized rods. This is a larger return compared to galvanized rods for a marginal initial cost increase.

For certain situations, stainless steel ground rods may be specified. According to the NEGRP, these ground rods offer a service life of around 50 years. In highly corrosive environments—such as at industrial plants or salty environments (e.g. ocean beaches)—stainless steel outlasts copper-bonded ground rods.


The chart above articulates a clear gap in service life for zinc galvanized ground rods when compared to its alternatives.

To clearly evaluate the value of each material, we can compare each material in terms of annual cost. If we now know zinc galvanized rods may need to be replaced twice before a copper-bonded or stainless steel rod does once, how does that translate into cost?


From a value perspective, stainless steel is the clear loser, explaining why it is only specified when absolutely necessary due to its high initial cost.

When comparing galvanized and copper-bonded ground rods, both copper-bonded products offer an annual cost advantage.

Dive Deeper on Grounding Systems

Choosing the appropriate ground rod is only one important factor in a comprehensive grounding system. View the ERICO Grounding, Bonding and nVent ERICO Cadweld Solutions Guide for an overview of facility electrical protection and where grounding fits in.
