Protection Relay Test Kit MCRT40
Main Functions
1) With 4 Phase voltage & 3 Phase current output, can test various of protection relay
2) 4th phase voltage Ux is multifunction voltage and can be set as 4 kinds of 3U0 or test testing synchronous
voltage, or any voltage value output.
3) Easy to operate with using rotation mouse and display by large LCD screen.
4) Can test all kinds of relay and micro-computer protections, also can simulate various complicated transient,
permanent&transformative fault to do whole group test
5) Can be operated by external PC, can test all kinds of object by software, also display vector diagram and
fault waveform, then can save the test records and print out.
6) Powerful software function: can finish various complicated test, such as three phase differential test,
line protection re-close test and etc…, and can test & scan various protection rated value, also can get
fault playback and real-time save test records, display vector diagram and then print out.
7) Switch signal:
7 circuits contact input and 2 pair idle contact output. Also this function can be extended
8) Large screen LCD display (320*240), with clear display.
9) With various protections inside, also with self-diagnose and interlock function.
10) With independent special DC power source output 110V&220V special-use adjustable DC source output.
