Crompton instruments

Integra multi-function metering systems measure, display and communicate over 100 parameters, including true RMS and power quality data. Fully programmable via a simple menu-driven interface, Integra systems can be integrated into energy management and SCADA systems. Options include pulsed, analog and RS-485 communication protocols, a choice of ANSI case-styles and LED or LCD displays.
Self-contained panel meters measure combined kWh or kVArh* with pulsed or analog output options and selectable CT and VT ratios, replacing separate rotating disc meters or instantaneous wattmeters. Microprocessor controlled circuitry provides up to Class 1.0 accuracy with outputs displayed directly on the instrument monitor or a remote PC.
Transducers measure, isolate, and convert electrical parameters into industry standard DC output signals and broadcast results via communication interface options such as RS232 and Modbus®. These vibration-resistant transducers protect against high voltage and overload. Integra transducers measure up to 50 electrical and power quality parameters and offer up to four user-programmable analogue outputs. Paladin transducers provide Class 0.5 or 0.2 measurement of up to seven electrical parameters and multiple analog outputs from a single housing.
Trip relays continuously monitor and protect any electrical parameter within a set point limit. The range offers both traditional and technologically advanced products, including single parameter units, earth leakage protection, ground fault relays, vector shift and ROCOF, and microprocessor system protection relays.
Comprehensive range of meter relays and digital indicators for measuring, monitoring and control of any electrical or process parameter. Meter relays are ideal for process control and load shedding applications, combining an indicator with set points which trigger alarm and control circuits when the signal deviates from set limits. This range includes digital and analog meter relays, digital bargraph indicators and controllers. Instruments are designed for control panels and switchboards, monitoring systems, power generation and control applications.
Comprehensive range of analogue instruments for measuring electrical and electronic parameters. Range includes ANSI switchboard meters, panel indicators, sealed and ruggedised 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.
Complete range of 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, balanced and split cores, current ratings and various mounting options.
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.
Generator-set control units provide integrated management of all combined heat and power, cogeneration, diesel and gas engine generator applications. Units monitor energy supply within pre-set limits, automatically starting generator motors and transferring loads between mains and generator as needed. Units can be programmed to monitor a variety of energy parameters directly or through a remote PC.
