When the wiring type of the relay protection tester transformer is YY (Y0), the wiring of the test is very simple: when testing phase A, the tester IA is connected to the phase A of the high voltage side of the protection, and the tester IB is connected to the low. When the wiring type of the relay protection tester transformer is YY (Y0), the wiring of the test is very simple: when testing phase A, the tester IA is connected to the phase A of the high voltage side of the protection, and the tester IB is connected to the low. Connect the Test Set: Use the relay test set to apply voltage and current signals to the relay. Simulate Faults: Test various fault scenarios (e. Verify Settings: Ensure the relay operates within its specified settings. The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. Modular, multi-phase protection relay test set and commissioning tool Compact relay test set for. Although testing of individual components may take place on a regular basis (e. Critical. The purpose of this Standard Work Practice (SWP) is to standardise and describe the method for testing of Ergon Energy protection relays for commissioning purposes. This SWP should be interpreted in conjunction with Standard for Substation Protection (V1.
