6 Phase Current + 4 Phase Voltage Test Set and Commissioning Tool | CMC 356

The CMC 356 is the universal solution for testing all generations and types of protection relays. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands.

The CMC 356 is the first choice for applications requiring the highest versatility, amplitude and power. Commissioning engineers will particularly appreciate its ability to perform wiring and plausibility checks of current transformers, by using primary injection of high currents from the test set.

The analog test signals are generated digitally using DSP technology. This, in combination with the use of additional error correction algorithms, results in accurate testing signals even at small amplitudes.

The six current and four voltage output channels are continuously and independently adjustable in amplitude, phase and frequency. All outputs are overload and short-circuit proof and are protected against external high-voltage transient signals and over-temperature.

The integrated network interface supports comprehensive testing in the IEC 61850 environments using optional GOOSE simulation and subscription and Sampled Values simulation functionality.

Up to 12 independent channels with low-level signals are available at the back of the test set, which can be used to test relays which have a low-level input facility or to control external amplifier units.

By utilizing the EnerLyzer software option, the ten binary inputs of a CMC 356 equipped with the ELT-1 hardware option alternatively work as analog measurement inputs.

The unit then can also be used as a multifunctional multimeter and transient recorder. Besides its operation with the powerful Test Universe software running on a PC, the CMC 356 can also manually be controlled with the highly flexible CMControl unit and the CMControl App running on an Android Tablet or a Windows PC.
