<![CDATA[TE Connectivity Foundation continues global effort to increase access to STEM education]]> https://www.colterlec.com.au/news/postte-connectivity-foundation-continues-global-effort-to-increase-access-to-stem-education https://www.colterlec.com.au/news/postte-connectivity-foundation-continues-global-effort-to-increase-access-to-stem-education Fri, 19 Jul 2019 00:00:00 GMT  

Karen Leggio, chair of the TE Foundation Board of Trustees and a senior vice president at TE Connectivity, a global leader in sensors and connectors, said: "We initiated our support of this work last year, and were thrilled not only with what these organizations achieved, but with how they plan to evolve their work going forward. Each one of them took our mandate to impact underserved populations by providing access to education and careers in engineering and technology very seriously, and is focusing even more keenly on our shared goals as they look to the future."

Girl Up, a global leadership development initiative started by the United Nations Foundation, now seeks to incorporate STEM into its overall leadership development programming – an evolution from the TE Foundation's first grant which provided support for separate STEM activities. Girl Up plans to use the TE Foundation's grant to bring its STEM for Social Good program to scale, reaching more diverse girls through rural and urban outreach and the creation of partnerships with schools and local organizations. More specifically, the TE Foundation's grant will provide funding for three STEM for Social Good tour stops in new underserved U.S. rural and urban markets and two STEM for Social Good events in new international markets. It will also allow Girl Up to translate the STEM for Social Good Toolkit into other languages to help mobilize leaders in more countries (Spanish and French in 2019 with additional languages to come in 2020), and support building partnerships with national and international school and teacher networks.

Anna Blue, co-executive director of Girl Up, looks forward to continued collaboration with the TE Foundation: "We believe both that impact starts with access, and also that girls are the most powerful force for change. With the support of the TE Foundation, we are connecting girls globally to how they can make their mark on the world through STEM, igniting their confidence to use their unique perspective to create solutions for social good in their communities and the world."

SMASH has a stated goal of providing access to technology and engineering for underserved students of color and has a proven track record of success. Its free, multi-year college prep program, SMASH Academy, currently operates in several regions in the U.S. The initial TE Foundation grant not only enabled the organization to open a program at the Wharton School at the University of Pennsylvania, but also supported an expanded platform to house an alumni network. Going forward, the TE Foundation grant will support the completion of the three-year cycle for the inaugural class of students at Wharton, as well as enable the next two cohorts to begin. The TE Foundation has also worked with SMASH to create a TE Fellows Fund at SMASH/Wharton to provide direct financial support to those students.

TE Foundation funding will also continue to expand the SMASH alumni network, focusing on outreach, programming and conference attendance to help support those who have gone through the program as they move into college and beyond, thereby increasing the likelihood that these students will engage in STEM careers.

"TE Connectivity has catalyzed the innovation and growth of SMASH. Their funding and support of our programming allows us to expose hundreds of our young people to cutting edge STEM and business education in partnership with Wharton, grow our internship program for SMASH Alumni, and pilot a new program that will ensure our scholars can participate in SMASH and meet the financial needs of their families. TE's commitment to SMASH and increasing STEM access overall is undeniable," said Eli Kennedy, CEO of SMASH.

FIRST Global runs high-profile, international robotics competitions designed around solving major global challenges with high school aged participants who are ethnically, socio-economically and gender diverse, inspiring not only those who participate, but also those who watch and follow these events around the world. The TE Foundation grant will help extend the competition to additional nations where girls are not typically given the opportunity to partake in education or STEM opportunities and help provide the kits needed for the competition. The grant will also support the development of a website forum for participants to stay connected with the long-term goal of creating a formal Alumni Network as a potential avenue for future support.

"FIRST Global is creating opportunities and inspiring students around the world, thus giving them the necessary tools to solve the global challenges we are all faced with," said Dean Kamen, founder of FIRST Global. "We are so grateful for our partners, like the TE Foundation, that strongly believe in this mission and support what we are doing to create a better and brighter future.

TE Connectivity's corporate philanthropy also supports education and technology initiatives, as well as causes supporting health and human services. In fiscal year 2018, TE Connectivity donated $4.1 million in charitable grants to support these causes in the communities where TE employees live and work around the world.

<![CDATA[Danfoss APP pumps and iSave 21 Plus enable solar-powered desalination]]> https://www.colterlec.com.au/news/postdanfoss-app-pumps-and-isave-21-plus-enable-solar-powered-desalination https://www.colterlec.com.au/news/postdanfoss-app-pumps-and-isave-21-plus-enable-solar-powered-desalination Fri, 19 Jul 2019 00:00:00 GMT

Taking water from the sea, the plant provides people in the historically drought-prone region with up to 100,000 liters (26,417 gallons) of safe, drinkable water per day.

The seawater reverse osmosis (SWRO) conversion process uses a Danfoss APP pump to force water through a desalination membrane under high pressure. The water’s kinetic energy then drives the iSave 21 Plus energy recovery device.

Specifically developed for SWRO applications, the Danfoss iSave 21 Plus recovers kinetic energy that would otherwise be lost and returns it to the plant. Meanwhile, APP pumps provide leading levels of energy efficiency and a high level of pressure, thanks to its unique design. The APP pump’s simple construction also makes it compact—with very little maintenance required—ideal for remote sites. What’s more, it’s oil free, so the risk of unplanned downtime is significantly reduced and there’s zero potential for water contamination. 

Kevin Evald, Product Manager at Danfoss HPP, explains: “SWRO isn’t a new concept. But being able to use PV power brings a whole new realm of possibilities—with the potential to bring a reliable supply of fresh water to remote, rural, and developing parts of the world.”

"The Danfoss APP pump—used in conjunction with the iSave 21 Plus—enables exactly that. The OSMOSUN® plant is Africa’s first to be powered solely using PV solar energy. What’s more, the components’ simplicity means longer maintenance intervals and far greater reliability, which is ideal for installing the plant in places where servicing would be a challenge."

See news story from SABC News

Mascara’s OSMOSUN® system is already proven in other parts of the world (we have a more detailed story about its PV-powered SWRO plant in Abu Dhabi). At full capacity, it can produce approximately 300,000 liters (79,260 gallons) of water per day, using 400m2 of PV panels.

Features that make the APP pump ideal for SWRO use include:

Complete product range—offering pressure, flow, speed, and size to meet your needs

Compact design—half the size of alternative pumps and ideal for applications where space is limited 

Long service intervals—with simple, reliable operation and servicing

No risk of contamination—due to a self-lubricating, oil-free design

Super Duplex and Duplex construction—ideal for salt water operations

In addition, benefits of the Danfoss iSave 21 Plus include:

Up to 60% reduction in energy consumption—by utilizing otherwise lost kinetic energy

Substantial Capex and Opex savings—due to high efficiency and low maintenance

Three-in-one solution—simple installation and low Capex

<![CDATA[IEEE 837 Explained: How Permanent Grounding Connections Are Qualified]]> https://www.colterlec.com.au/news/postieee-837-explained-how-permanent-grounding-connections-are-qualified https://www.colterlec.com.au/news/postieee-837-explained-how-permanent-grounding-connections-are-qualified Fri, 19 Jul 2019 00:00:00 GMT When electrical professionals install grounding systems, they need to have confidence that the design and installation will assure protection reliably for the expected life of the system. Grounding connections are the most susceptible link in the grounding system to corrosion since they are buried in soil.

To confirm reliability of permanent grounding connections, IEEE 837 is the most rigorous and highly regarded grounding connection testing standard in the world.  Specifically developed for substation grounding, this standard is considered state of the art for all who are concerned about safety and reliability of grounding.

The Institute of Electrical and Electronics Engineers, Inc. (IEEE) is the world’s largest technical professional organization, and it boasts nearly 1,300 standards that are under development or in use.

In this post, we seek to answer this question: How can engineers, owners, and installers ensure that permanent grounding connections meet Standard IEEE 837 and will remain dependable throughout the grounding system’s life?

What Is IEEE 837?

Last updated in 2014, IEEE 837 is the “Standard for Qualifying Permanent Connections Used in Substation Grounding.” As the name states, it provides direction and methods for qualifying permanent connections used for substation grounding.

The Standard IEEE 837 is one of the most difficult standards to pass for grounding connections. Traditional mechanical connectors have been found both within these tests, and by customers in real world, to fail or deteriorate significantly when subjected to faults and corrosive environments. As discussed in our previous post, exothermic connections create a molecular bond between grounding conductors to form a single, solid connection, that are less susceptible to corrosion than mechanical grounding connections over the life of a grounding system

In particular, Standard IEEE 837 addresses:

  • Connections used within the grid system.
  • Connections used to join ground leads to the grid system.
  • Connection used to join the ground leads to equipment and structures.

The standard applies to testing connections joining copper, steel, copper-bonded steel, copper-clad steel, galvanized steel and stainless steel.

The purpose of IEEE 837 is to:

  • Assure users that connections will perform reliably over the lifetime of the installation.
  • Test the connections for heat and mechanical forces using an Electromagnetic Force Test.
  • Satisfy connection criteria outlined in IEEE Standard 80, the Guide for Safety in AC Substation Grounding.

This standard defines a repeatable test program that enables connection manufacturers to qualify their products as permanent grounding connections. Upon passing the test, users can be confident that the qualified permanent grounding connection is capable of performing reliably over the lifetime of the installation.

IEEE 837 Test Overview

The tests are intended to ensure the reliability of grounding connections to withstand mechanical stress and heat, during the Electromagnetic Forces (EMF) Test and accelerated corrosion or sequential test.

What must be tested?

  • Each style or family of connection. For example, crimped lug connections and lugs using bolted pressure plates to secure the cable are considered different styles. Therefore, both connectors are required to be tested to qualify the styles.
  • A connector’s broadest combination range. When a connector design allows for a range of conductors, each of the tests must be performed on the “largest to largest” combination as well as the “largest to smallest” combination.
  • Individually and sequentially. Each style, combination and sample must be tested separately to ensure a fair and uninfluenced test.
  • Connectors with all relevant materials. For example, if a connector can be used on copper and copper-bonded steel, then it must be tested with both conductor types.

Each of these requirements makes the test more rigorous, and thus more reliable in its field applications.   Third party test labs are required for these tests to avoid potential conflicts of interest inherent in self-certification (or place this somewhere else).

Two categories of tests must be performed to assess the connection: mechanical tests and sequential tests.

Mechanical Tests

The mechanical test, or electromagnetic force (EMF) test, is conducted to determine if electromagnetic forces would damage the connection during a fault.

During the test, four samples (each tested separately) are subjected to two 15 cycles of a severe current.


Sample Waveform for 4/0 AWG Conductor

The pass/fail criterion is based on the movement of the conductor. The connector must not fail– overheat, or allow cable slippage – and shall not exceed either 10 mm of slippage or the outer diameter of the conductor, whichever is less. The edge of the connection is marked prior to the testing, then measured to the connector following the tests.


Movement Illustration

Sequential Tests

These tests, performed in sequence on the same samples, monitor accelerated corrosion, the connection’s reliability and performance. There are four sequential tests as part of IEEE 837.

Current-temperature cycling. When fluctuating currents cause temperature changes, does the connection continue to conform to resistance criteria?

Freeze-thaw test. When subjected to repeated cycles of freezing and thawing in water, is connection resistance maintained?

Corrosion tests. Two tests are designed to evaluate the corrosion resistance of the connections. The two tests:

  • Salt spray (for above ground applications). Measures the corrosive effect of salt spray (i.e. sodium chloride) on the connections.
  • Nitric acid (for direct burial applications). Measures the effects of acid attack, specifically nitric acid (HNO3), on connections.

Fault-current tests. Test to determine if connections subjected to the previous tests will withstand fault-current surges.

The electric motorcycles will be used for the first time at the start of the FIM Enel MotoE World Cup at Sachsenring on 7 July 2019. Energica is the only manufacturer represented at the World Cup.

A fire in March 2019 destroyed all racing machines, so that the original start of the MotoE racing series had to be postponed to July. All vehicle charging inlets installed in these newly produced machines were sponsored by Phoenix Contact E-Mobility.

The CCS inlets enable both conventional AC and fast DC charging. The CCS charging interface offers maximum safety during the charging process. Monitoring the temperature at the power contacts is part of a safe charging process. Overheating due to high outside temperatures or overload is detected by the PT1000 resistance sensors. Another safety feature is the electromechanical locking bolt, which locks the charging connector in the vehicle inlet during the charging process, making it impossible to remove the charging connector under load.

<![CDATA[How to detect compressed air, gas and vacuum leaks AND find hidden profits]]> https://www.colterlec.com.au/news/posthow-to-detect-compressed-air-gas-and-vacuum-leaks-and-find-hidden-profits https://www.colterlec.com.au/news/posthow-to-detect-compressed-air-gas-and-vacuum-leaks-and-find-hidden-profits Tue, 11 Jun 2019 00:00:00 GMT Yet many compressed air, gas and vacuum systems are compromised by wear and poor maintenance practices, which contribute to the greatest waste of all—the ever-present leaks. These leaks can be hidden behind machines, at connection points, overhead in fixed pipes, or in cracked pipes or worn hoses. The waste adds up quickly and can even lead to downtime.

The high cost of wasted air

According to the U.S. Department of Energy, a single 1/8” (3mm) leak in a compressed air line can cost upwards of $2,500 a year. The U.S. Department of Energy estimates an average U.S. plant that has not been well maintained, can waste 20 % of its total compressed air production capacity through leaks. The New Zealand government, as part of its Target Sustainability project, estimates that system leaks can account for 30 to 50 % of a compressed air system’s capacity. Quick detection of compressed air, gas and vacuum leaks is a single factor in finding hidden profits. Air leaks can also lead to capital expenses, rework, downtime or quality issues and increased maintenance costs.

To make up the pressure loss due to leaks, operators often overcompensate by buying a larger compressor than is needed, which requires significant capital costs along with increasing energy costs. System leaks can also cause air dependent equipment to fail due to low system pressure. That can lead to production delays, unplanned downtime, quality issues, decreased service life, and increased maintenance due to unnecessary cycling of compressors.

The maintenance manager of one United States manufacturer, for instance, says low pressure in one of their air torqueing tools can potentially lead to product defects. “Mis-torqued units, either under torqued or over torqued, can lead to recalls. That also leads to more man hours put into something that should have been a very standard process,” he says. “It’s money out the door in lost profits and lost units. In the worst-case scenario we also wind up with lost demand because we weren't able to deliver.”

It’s no wonder that utilities, industry, and government all target compressed air systems as a potential source of cost savings. Leaks lead to waste. Correcting those leaks can save the operator money and prevent the utility from having to build additional capacity into their system.

Finding and fixing leaks isn’t easy

Many plants and facilities do not have a leak detection program. Finding and fixing leaks isn’t easy. Quantifying the amount of waste and determining the cost, requires energy specialists or consultants who use energy analyzers and loggers to audit your air systems. By systematically calculating the annual cost savings of eliminating the leaks, they can make a strong business case for proceeding on such a project.

Energy audits of compressed air systems are often conducted through partnerships with industry, government, and nongovernmental organizations (NGOs). One such partnership, the Compressed Air Challenge (CAC) is a voluntary collaboration of those types of groups. Its single goal is to provide product-neutral information and educational materials to help industries generate and use compressed air at maximum sustainable efficiency.

Why ultrasonic leak detection is inefficient

Mainstream leak detection practices are, unfortunately quite primitive. An age-old method is to listen for hissing sounds, which are virtually impossible to hear in many environments and to spray soapy water on the area of the suspected leak, which is messy and can create a possible slipping hazard.

The current go-to tool for finding compressor leaks is an ultrasonic acoustic detector–a portable electronic device that recognizes high frequency sounds associated with air leaks. Typical ultrasonic detectors help find leaks but they’re time consuming to use and repair crews can generally only use them during planned downtime, when maintaining other critical machines might be a better use of their time. These units also require the operator to be located close to the equipment to find leaks, which makes it difficult to use in hard-to-reach areas such as ceilings or behind other equipment.

In addition to the time it takes to find leaks using either soapy water or ultrasonic detectors, there can be safety issues with finding leaks overhead or under equipment using these techniques. Climbing ladders or crawling around equipment can pose dangers.

Compressed air leak detection game changer

What if there were a leak detection technology that could pinpoint the precise location of a leak from up to 50 meters away, in a noisy environment, without shutting down equipment? Fluke has developed an industrial imager that does just that. Industrial maintenance managers are calling the Fluke ii900 Sonic Industrial Imager, a “gamechanger” in the pursuit of finding compressed air leaks.

This new sonic industrial imager—which can detect a broader range of frequencies than traditional ultrasonic devices–uses new SoundSight™ technology to deliver enhanced visual scans of air leaks, similar to the way infrared cameras detect hotspots.

The ii900 includes an acoustical array of tiny super sensitive microphones that detect both sonic and ultrasonic sound waves. The ii900 recognizes a sound source at a potential leak location and then it applies proprietary algorithms that interpreter the sound as a leak. The results produce a SoundMap™ image—a color map superimposed over the visible light image—showing exactly where the leak is. The results are displayed on the 7” LCD screen as a still image or a real time video. The ii900 can save up to 999 image files or 20 video files for documentation or compliance purposes.

Large areas can be scanned quickly which helps locate leaks much faster than with other methods. It also allows for filtering on intensity and frequency ranges. A team at a large manufacturing plant recently used two ii900 prototype units to locate 80 compressed air leaks in one day. The maintenance manager said it would have taken them weeks to find that number of leaks using traditional methods. By finding and fixing leaks quickly, the crew also saved potential downtime, which at this plant can cost an estimated $100,000 an hour in lost productivity.

Where to find leaks:

  • Couplings
  • Hoses
  • Tubes
  • Fittings
  • Threaded pipe joints
  • Quick disconnects
  • FRLs (filter, regulator, lubricator combinations)
  • Condensate traps
  • Valves
  • Flanges
  • Packings
  • Pneumatic holding tanks


How much air are you wasting?

The first step in controlling leaks in compressed air, gas and vacuum systems is to estimate your leak load. Some leakage (less than 10 %) is to be expected. Anything beyond that is considered wasteful. The first step is to determine your current leak load so you can use that as a benchmark to compare improvements against.

The best method for estimating leak load is based on your control system. If you have a system with start/stop controls, simply start your compressor when there is no demand on the system—after hours or off shift. Then take several readings of compressor cycles to determine the average time to unload the loaded system. With no equipment running, the unloading of the system is due to leaks.

Leakage (%) = (T x 100) ÷ (T + t)T = onload time (minutes), t = offload time (minutes)

To estimate leak load in systems with more complex control strategies, place a pressure gauge downstream from the volume (V, in cubic feet), including all secondary receivers, mains, and piping. With no demand on the system, except leakage, bring the system up to its normal operating pressure (P1, in psig). Select a second pressure (P2, about half the value of P1) and measure the time (T, in minutes) it takes for the system to drop to P2.

Leakage (cfm free air) = [(V x ( P1 – P2) ÷ (T x 14.7)] x 1.25

The 1.25 multiplier corrects leakage to normal system pressure, thereby accounting for reduced leakage with decreasing system pressure.

Efficiently fixing and repairing leaks can lead to substantial cost reduction for air-dependent businesses. Companies are not only able to save on energy use by repairing leaks but can also improve production levels and extend equipment life.

<![CDATA[WHAT IS ENERGY EFFICIENCY?]]> https://www.colterlec.com.au/news/postwhat-is-energy-efficiency https://www.colterlec.com.au/news/postwhat-is-energy-efficiency Tue, 11 Jun 2019 00:00:00 GMT REDUCTION OF THE ENERGY CONSUMPTION

How are energy efficiency and respect for the environment linked? Energy efficiency is the desire to reduce the amount of energy required by a product or service. The use of a machine or other equipment produces heat, and therefore energy. Inevitably, there is a loss of the latter: the goal is to limit it.

Indeed, with regard to industrial electrical socket outlets, several factors must be taken into account:

- The heating due to the passage of the current;

- The thermal cycle linked to multiple "start & stop" maneuvers;

- Corrosion resistance (which adds additional heating).

Our flagship product, the DECONTACTOR™, has been developed to meet these criteria, with limited contact heating and better compensation of the thermal cycle through our butt-style contact technology.


The quality of the material is essential in the choice of an electrical socket outlet, since it impacts the duration of the product. Therefore, a product with a poor craftsmanship will need to be changed regularly. To limit this negative impact on the environment, costs and time optimization, MARECHAL ELECTRIC offers the possibility to change only the worn or broken part of the plug and not its entirety.


Finally, the company pays particular attention to the quality of its products: all are made in France, in accordance with international standards. Their robustness has an undeniable impact on their life span.


Energy efficiency is a concern for us, and at the heart of essential issues of our time.

Spring is underway, and with warmer weather comes an increased risk of severe weather—especially lightning. Electrical professionals need to educate their clients about surges and inform them of the basic efforts that can be employed to protect against costly power surges.

Here are five quick surge protection tips that people need to know:

  1. Use point-of-use surge protection devices (SPDs), which protect electronics and appliances when combined with a good grounding system.
  2. Have you or another professional check to ensure that the grounding system is up to code before installing any new surge protection.
  3. Present the option of panel SPDs, which mount in or on the main the main electrical panel to provide protection for the entire electrical system.
  4. To protect individual appliances, install point-of-use surge devices, such a surge strip.
  5. To enhance surge protection in the home, combine point-of-use devices with service entrance protection or an electrical panel surge protector.

For a more comprehensive explanation of the most important tips for storm season preparation, check out the full post.

Quick Clarification on Lightning Protection Systems and Bonding

On EC&M’s website, Mike Holt answered the following question, which ties in with the previous article:

Is it good practice to bond the lightning protection system to the building grounding electrode system?

Not only is it a good practice, but the NEC requires lightning protection systems to be bonded to a facility’s grounding electrode system. The connection minimizes the difference potential between the lightning protection system and the electrical system, thus reducing arcing between metal parts within the building. Refer to the full article on EC&M’s website for more information.

7 Common Electrical Code Violations

Based on an interview with a state chief electrical inspector and seasoned field inspector, Construction Pro Tips came away with the following common electrical code violations that cause a failed inspection:

  1. Choosing the wrong circuit breaker
  2. Forgetting the taper-resistant receptacles
  3. Wiring switches without a neutral
  4. Using a ground rod electrode when a better system is available
  5. Crowding a service panel
  6. Not enough receptacles in the foyer

This is becoming problematic because even though the Industrial Internet of Things is helping to connect more and more devices, it is, unfortunately, increasing network complexity and introducing new security risks. Without network visibility, it is very difficult to identify the root cause of problems. Control engineers often have to revert to trial and error to get the system back to normal, which is time-consuming and troublesome.

What if control engineers had clear visibility of the network status and could quickly identify the root cause of network downtime?
