Protection Relay Test Kit MCRT43
Main Functions
1) Four Phases voltage & Three Phases current output, can test various of protection relay
2) Convenient operation by using mouse and big LCD screen.
3) Able to test various relays and micro-computer protections devices
4) Also able to simulate different complicated transients, permanent&transformative faults to
do complete group test
5) Two operation way: in-built computer (operated by mouse) and by external PC, able to test various
relays by software, show vector diagram and fault waveform, then save test records and print out.
6) Strong software function:
Able to complete various complicated test, such as three phase differential test,
line protection re-close test and etc…, and can test & scan various protection rated value;
can get fault playback and real-time saving test records, showing vector diagram and print out.
7) Big LCD display (800*600)
8) Adopts reasonable cooling structure, and various protections inside and soft-start function,
9) with self-diagnose and interlock function.
