The Omicron 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.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. As a universal testing and commissioning solution, the Omicron CMC356 is the ideal option for many systems and scenarios. By generating analog test signals and combining them with additional error correction algorithms, accurate testing signals are created, even at small amplitudes.

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.
