A relay protection tester is a device used to test and calibrate relay protection devices. Copyright Goverment of Brunei Darussalam. These testers replicate numerous fault events and operational scenarios to ensure that the relays respond correctly. Protection relays play a key role in modern energy systems. Therefore, they must work reliably at all times.
The CMC 356 is the universal six-phase testing solution for all generations and types of protection relays, where highest versatility, amplitude and power are required.
