The three-phase microcomputer relay control tester has a 4-phase voltage 3 phase current output, which is suitable for various types of relay protection devices. The microcomputer relay control tester uses a high-speed high-performance digital signal processor comparative speed, transmission frequency bandwidth, and software application bifurcation algorithm produces each of the respective high-precision waveforms. Due to the integrated structure, each part is closely coupled, the data transmission distance is short, and the structure is compact.
