Introduce：
YN-MT relay protection test instrument with 6 phase voltage 6 phase current, 3 phase voltage 3 phase current of many types. Six way current output, six voltage output, current 30A/ phase, voltage 125V/ phase, with the subway special electric iron differential menu, convenient relay protection test. Two types have eight switch input, four way switch output, which can be used by users. That can test line protection, transformer protection, generator protection, conventional relays, state sequence, and other functions. That is indispensable test equipment for electric power, rail transportation industry.
