Power Measurement, Control and Protection Solutions

Crompton Instruments offer an extensive range of products designed for themeasurement, control, analysis and communication of power and energy consumption, and power quality data. Crompton has earned a world wide reputation for innovation, quality, service and technical expertise for a diverse array of industries and applications.

Integra Digital Metering Systems

A comprehensive range of high accuracy multi function digital metering systems offering measurement, display and communication of over 100 parameters, including true RMS measurement for total harmonic distortion and power quality data. Integra products are fully programmable via a simple menu driven interface and can be integrated into energy management systems via RS485 Modbus, Johnson Controls, Lonworks or Profibus interface options. To suit requirements, Integra offers pulsed, analogue and digital output options, and a choice of DIN, ANSI and JIS case styles, with high quality LED or LCD display.

Kilowatt Hour Energy Meters

An innovative range of panel mounted or DIN rail mounting meters ideal for monitoring energy consumption. These self contained meters offer combined kW.h or kVAr.h energy measurement, with pulsed or analogue output options and selectable CT and VT ratios, thus replacing the need for rotating disc meters and separate instantaneous wattmeters. Microprocessor controlled circuitry provides up to class 1.0 accuracy, which can be displayed via electro-mechanical or LCD counters, or various integral instantaneous indication options.

Transducers

An extensive range of high specification transducers providing measurement,isolation and conversion of electrical parameters into industry standard DCoutput signals, with communication interface options of RS485 Modbus,Lonworks and Profibus. Integra 1560 and 1580 multi function transducer systems offer up to 4 user programmable analogue outputs, and measurement of up to50 electrical and power quality parameters, including THD. The Paladin range ofDIN rail transducers offer multiple analogue outputs from one housing, and class 0.5 or 0.2 measurement of up to seven electrical parameters, including true RMS sensing.

Protector Trip Relays

A comprehensive range of electronic control products, providing continuousmonitoring and protection of any electrical parameter. When the monitoredparameter deviates from the desired set point limit, the relay will operate toprotect the power asset. Designed to suit a wide variety of applications, the range offers both traditional and technologically advanced products, including single parameter units, earth leakage protection, ground fault relays, vector shift and ROCOF, and multifunctional microprocessor based system protection relays.

Meter Relays

A comprehensive range of meter relays offering measurement, monitoring and control of any electrical or process parameter. Relays combine a highly accurate indicator with high and low set points, which operate alarm and control circuits when the monitored signal value deviates from the set point limits. The rangeincludes digital and analogue meter relays, and digital bargraph indicators andcontrollers, ideally suited for process control and load shedding applications.
