Technical Index

With 4 Phase voltage & 3 Phase current output, can test various of protection relay.

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.

Easy to operate with using mouse and display by large LCD screen.

Can test all kinds of relay and micro-computer protections, also can simulate various complicated transient, permanent & transformative fault to do whole group test.

Double operation mode: in-built computer (operated by mouse) and also 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.

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.

Switch signal:10 circuits contact input and 8 pair idle contact output. Also this function can be extended based on customer requirements.

Large screen LCD display (800*600), with clear display.

Adopting reasonable cooling structure, and with various protections inside and soft-start function, also with self-diagnose and interlock function.

With independent special DC power source output 110V&220V special-use adjustable DC source output.
