Testing and Maintenance of Protective Relays
Differential relays are tested for heavy currents to make sure that the relay does not operate for through faults. Special equipment is used for heavy current testing.
Operation, maintenance, and field test procedures for protective relays
Although testing of individual components may take place on a regular basis (e.g., relay calibration and lockout relay testing), it is essential to test the entire protection circuit, including
