    Brunei Relay Protection Tester Principle

    A relay protection tester is a core device used to verify the performance of relay protection devices. Its working principle can be summarized as “signal excitation – behavior detection. The recommended test modules for relay tests are: DC test, AC and DC test, AC test, differential test, differential harmonic test, Power impedance, power direction. When the transformer wiring type is Y/Y (Y0), the test wiring is very simple: when testing phase A, the tester IA is connected to the phase A of the high voltage side, and the tester IB is connected to the phase a of the low voltage side. After the neutral line of the high and low voltage sides is.
