Why does the relay tester need to output 6-phase current and 6-phase voltage
The microcomputer relay protection tester needs to output 6-phase current and 6-phase voltage, mainly to achieve more comprehensive and accurate testing. Specifically, the core of the six-phase microcomputer relay protection tester is the use of the latest generation of high-speed DSP digital signal processor, with dual-male 12-bit DAC and full-fidelity high-performance linear amplifier, which can provide high precision, good waveform, and stable performance.
First of all, the output mode of six-phase current and voltage can be compatible with the testing of various relays and protective devices in traditional and modern times. For example, for the testing of standby self-throwing devices and microcomputer differential protection devices, it is necessary to target various relay calibration procedures.
Secondly, through the flexible combination of voltage and current output, the conventional 4-phase voltage 3-phase current type, 6-phase voltage type, 6-phase current type, and 12-phase current type output mode can be realized. This is very beneficial for the differential test of three-phase transformer and the quick cutting of plant power and standby self-injection test.
Finally, the built-in high-configuration industrial computer, imported true color LCD screen and other designs make the test process more convenient without any external auxiliary equipment. Therefore, the microcomputer relay protection tester needs to output 6-phase current and 6-phase voltage to achieve more efficient and comprehensive testing.
