The next generation of protection relay test set and commissioning tool.

The CMC 356 is the universal solution for testing all relay generations and types. It is designed for protection testing of electromechanical relays as well as for testing modern IEC 61850 IEDs. The CMC 356 is the ideal tool for various testing tasks in substation commissioning and maintenance. It is the first choice for all applications requiring the highest versatility, amplitude and power.

The CMC 356 is designed to optimally cover the modern requirements for commissioning and maintaining substations and protection devices. It opens up new possibilities especially for applications with 5 A CTs and for tests with very high power demand. Its specifications cover applications in generation (including distributed generation), transmission, distribution, industry and railways - in high, medium and low voltage levels.

The special feature of the CMC 356 are the powerful current sources with great dynamic range. Commissioning engineers will appreciate the possibility to perform wiring and plausibility checks of the current transformers, by primary injection of high currents from the test set.Three-phase testing of high-burden electromechanical relays and the latest IEC 61850 technology in one device is the answer to the wide variety of challenges in today's protection engineering.
