Six phase microcomputer relay protection testerDeveloped using modern digital technology, high-precision electronic devices, microcomputer systems, and new circuits and structures. It can independently complete device testing in professional fields such as microcomputer protection, relay protection, excitation, metering, and fault recording, and is widely used in scientific research, production, and electrical testing sites in industries such as power, petrochemicals, metallurgy, and railways.

Six phase microcomputer relay protection testerMeet all on-site testing requirements. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices, making testing more convenient and efficient.It has a standard six phase current and six phase voltage output simultaneously, with a current of 30A/phase and a voltage of 125V/phase. Six phase current parallel connection can reach 180A.

The main control board of the six phase microcomputer relay protection tester adopts DSP+FPGA structure, 16 bit DAC output, and can generate high-density sine waves of 2000 points per week for the base wave, greatly improving the quality of the waveform and enhancing the accuracy of the tester.
