Three Phase Protection Relay Tester
The Three phase relay protection tester can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronous, frequency, DC, intermediate, time, etc.) and microcomputer protection, and can simulate A variety of complex transient, permanent, and transitional faults are tested throughout the set.
It adopts a high-speed and high-performance digital signal processor with fast operation speed and transmission frequency bandwidth. The software uses double-precision algorithms to generate arbitrary high-precision waveforms of each phase. Due to the integrated structure, the parts are tightly combined, the data transmission distance is short, and the structure is compact.
