Home / What is the power rating of the relay protection test instrument
Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very high power demands. The CMC 356 is the universal solution for testing all generations and types of protection relays. The relay protection system is the core guardian and "brain" of a power grid's safe operation. For power engineering companies, testing agencies, and substation maintenance teams, purchasing a microcomputer protection relay test set is not just about acquiring a testing tool; it is a long-term. A Relay Protection Tester (RPT) is a high-precision, multi-channel, digitally synthesized, and microprocessor-controlled test instrument engineered for the comprehensive functional verification, dynamic performance evaluation, and time-domain accuracy validation of electromechanical, solid-state.
