Product Q&A

Q:What is the main function of a three-phase relay protection tester?

It is a specialized device designed to simulate various electrical fault conditions, verify the accuracy and reliability of protection relays, and ensure they can trip or operate correctly when electrical system faults occur.

Q:Can the tester be used for both low-voltage and high-voltage relay testing?

Most three-phase relay protection testers are compatible with low-voltage and medium-voltage relays directly; for high-voltage relay testing, they usually need to cooperate with matching voltage transformers (VTs) or current transformers (CTs) to achieve safe and accurate te

Q:What key parameters should be checked before starting a relay test with the tester?

You need to confirm the input voltage of the tester matches the power supply, set the correct test current, voltage, phase angle and frequency according to the relay's rated parameters, and ensure the wiring between the tester and the relay is correct and firm.

Q:How to solve the problem that the tester fails to communicate with the connected PC software?

First, check if the communication cable (such as USB or Ethernet cable) is properly connected and undamaged; then confirm the communication port settings on both the tester and the software are consistent; if necessary, restart both the tester and the PC to re-establish the connection.

Q:Is it necessary to calibrate the three-phase relay protection tester regularly?

Yes, regular calibration is essential. It is recommended to calibrate the tester at least once a year or in accordance with relevant industry standards to maintain the accuracy of its output current, voltage and other parameters, ensuring reliable test results.
