Advanced protection relay test system

Click2Contact

An advanced four-phase dynamic automatic protection relay test system, the Omicron CMC range is a universal system suitable for testing old and new generation relays, energy meters and transducers.

Routine testing is required on protective relays used in the operation of electric utilities, power plants and heavy industrial organisations. The process is simplified when using an advanced test system which calibrates and tests simple over-current relays, voltage relays and other protective devices.

The Omicron CMC256-EP produces reliable and accurate results, in a robust but portable design. The unit uses digitally generated test signals (known as DSP technology), resulting in highly accurate testing signals even at small amplitudes.

Due to the accuracy of the EP option it is possible to test energy meters of up to class 0.2S according to IEC without an additional reference meter. The system is also suitable for:

• relay manufacturers for their development process;
• type testing;
• acceptance testing;
• device calibration;
• product demonstrations.
