Ben Vincent, Relay Tech with Groton Utilities, Connecticut, talks about his experiences when using the OMICRON CMC 356 for testing electromechanical and digital overcurrent protection relays.

The CMC stores all output values, including magnitudes, phases, and frequencies, as well as all changes to the binary inputs together with the associated timings. It also allows for the addition of user comments, and the inclusion of diagrams.

Protective relays, energy meters, measurement transducers, and power quality devices are vital components of power systems. Regular testing of all these devices is necessary to ensure their reliability. OMICRON entered this industry in 1990 with the CMC, and quickly rose to its leading position through continuous innovation. And now, more than 10,000 CMCs are being used in more than 130 countries.

EnerLyzer is a software option for the CMC 256plus and CMC 356, which enables powerful analog measurement functions. It offers four modes of operation: multimeter, harmonic analysis, transient recording and trend recording. It allows each of the ten measurement inputs of the CMC to be reconfigured for measuring voltages of up to 600 V or, via shunts or current clamps, it can also measure currents.
