Relays take abuse during normal operation, so it is important to always check their condition. Regular checkups will negate problems before they worsen, or even start.
When it comes to the testing of differential protection relays, the Omicron CMC 356 Universal Relay Test Set and Commissioning Tool offers high powered solutions to engineers needing versatile equipment that can test multiple generations of differing types of relays.
For primary injection testing of current transformers, VTs or primary relays, the Omicron CMC 356 is also ideal. The high current amplitudes in parallel allow for checking current transformer polarities. The portably rugged case allows the set to be used in the field without worry of damage by weather or dirt conditions.
The Omicron CMC 356 has six current sources of up to 64 Amperes output which allows for the simulation of the operating conditions of high power relays. It can also test wiring checks on current transformers through primary injection testing. It comes with the Test Universe Software which helps enhance testing and test results analysis. This tool is chosen by many technicians and engineers in testing relays because of its high power output and its versatility.
