Relays are frequently found in high voltage or medium voltage power systems. With usage the relay connections deteriorate or get contaminated. Therefore, it’s in the interest of both the end user as well as the manufacturer to check the behavior of relays periodically.
The Omicron CMC 356 Universal Relay Test Set and Commissioning Tool’s analog test signals are generated digitally using DSP technology. This, in combination with the use of additional error correction algorithms, results in accurate testing signals even at small amplitudes.
