Microcomputer relay protection tester also known as three-phase microcomputer relay protection tester, three-phase microcomputer relay protection tester is a special power relay protection tester.Three-phase microcomputer relay protection tester has 4 phase voltage 3 phase current output, suitable for various types of relay protection device test.Three-phase microcomputer relay protection tester adopts high speed and high performance digital control processor as control microcomputer, and the software uses double precision algorithm to generate arbitrary high precision waveform of each phase.Because of the integrated structure, each part is closely combined, the data transmission distance is short, and the structure is compact.It overcomes the problem of low number of output waveform points caused by long data communication line and narrow frequency band in the measurement and control instrument directly controlled by laptop computer.
