A power plant needed to calibrate over 20 relay protection devices before a major grid upgrade, but single-phase testers were too slow and unable to simulate complex fault conditions.
Our Multifunctional Microcomputer Relay Protection Tester, with 6-phase voltage and current output, was used to simulate real-world fault scenarios and calibrate each device’s response.
The digital display and intuitive software allowed technicians to set parameters and record results quickly. The entire calibration project was completed in 3 days, compared to the expected 2 weeks with traditional equipment.
The power plant passed all grid acceptance tests on schedule, ensuring smooth operation of the new power distribution system.
