Crompton instruments became part of the TE Connectivity Group in January 2002. The Energy Division, is a global manufacturer of products and systems for the electrical power industry, and an operating unit of TE Connectivity.

Since 1881, Crompton products have been closely associated with high-quality technological developments in all aspects of electrical instrumentation. The Crompton range represents one of the largest product offerings of power measurement, control and protection instrumentation, for switchgear and generator set manufacturers, panel builders and OEMs. Crompton products offer proven reliability across a diverse array of industries including power generation, process control, test and measurement, utility, marine, defence and energy management applications.

Make smarter decisions on effective energy use. Introducing the new Crompton Instruments Integra 2270 Power Quality Meter. It monitors the quality of incoming electricity with a 0.2S% accuracy of the reading.


Integra Multi-function Metering Systems

Integra range of multi-function metering systems measure, display and communicate over 100 parameters. Integra systems can be integrated into energy management and SCADA systems. Options include pulsed, analogue and RS485 communication protocols, a choice of DIN, DIN-rail and ANSI case-stylesandLED or LCD displays.

For the full range of Integra Multi-function Metering Systems

Integra and Paladin Transducers

Extensive range of transducers providing measurement, isolation and conversion of electrical parameters into industry standard output signals, offering single or multiple analogue outputs within a single case housing.


kWh Meters

DIN-rail mounted or self-contained panel meters measure combined kWh or kVArh with pulsed or analogue output options and selectable CT and VT ratios.Microprocessor controlled circuitry provides up to Class 1.0 accuracy with outputs displayed directly on the instrument monitor or a remote PC.


Protector Trip Relays

Trip relays continuously monitor and protect any electrical parameter within a set point limit. This versatile range offers numerous trip functions for single and three phase power systems.

Analogue Instruments

Traditional range of analogue instruments includes ANSI switchboard meters, panel indicators, sealed and ruggedized instruments, and complementary selector switches for line-to-line and line-to-neutral readings. All instruments are available in a range of styles, sizes and performance specifications.


Current Transformers

Extensive range of current transformers for reducing high primary currents down to a consistent 5 or 1 Amp secondary current. Options include moulded case width, busbar and aperture sizes, tape wound, 3-in-1, balanced and split cores, current ratings and various mounting options.


Meter Relays and Digital Indicators

Meter relays and digital indicators are ideal for monitoring, process control and load shedding applications. This range includes digital and analogue meter relays, digital bar graph indicators and controllers.



Shunts provides an accurate dc millivolt signal, exactly proportional to the system current, to drive ammeter indicators, overload protection and control devices. This range includes industrial, switchboard, DEF 66-13, DIN, base mounted, tag end, lightweight and panel meter shunts in a variety of formats and configurations.
