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 example, the Omicron CMC 356 is also capable of providing the outputs necessary to test instrument transformers and higher burden relays. Additionally, this instrument is both rugged and portable, making it a great tool for use in field applications without the added concern for its continued use in harsh environments .
The CMC 356 has six current sources of up to 32 Amps of output current and 430 VA per channel. When configured for a 3 phase system the outputs can reach twice that of the individual current channels per phase. This high powered capability allows for the simulation of the operating conditions even for higher burden electro-mechanical relays.It can also be used to perform wiring checks on current transformers through primary injection testing. The CMC 356 comes with the Test Universe Software which helps enhance testing and the analysis of test results . This tool is chosen by many technicians and engineers in testing relays because of its high power output and its versatility.
