CMC 356
Test Sets
CMC 356: 6 Phase Current + 4 Phase Voltage Test Set and Commissioning Tool
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. Commissioning engineers will particularly appreciate
the possibility to perform wiring and plausibility checks of current transformers, by using
primary injection of high currents from the test set. The CMC 356 is the first choice for
applications requiring the highest versatility, amplitude and power. The CMC 356 can either
be operated by the Test Universe software running on a PC or by the front panel control device
CMControl.

With the unique PermaSync functionality (supported by TU 2.30 or higher), analog
and Sampled Values outputs stay permanently in sync with the internal CMC time
reference. In combination with the optional CMIRIG-B interface box, PermaSync
additionally allows the continuous synchronization of the output quantities with
an external IRIG-B time protocol or an external PPS signal. With CMIRIG-B it is also
possible to transmit the internal PPS signal of the to the device under test (e.g. PMUs
or IEDs stimulated with a synchronized Sampled Values data stream).
