Functional Testing of Relay Protection System
One approach to test the total protection system is to use primary injection techniques (see appendix H) that trigger protective relays and lockout relay, trip circuit breakers, and initiate annunciations and indications. This technique also tests the CT or PT ratios . Primary Injection Test Kit – for injecting large currents directly into CT circuits. Digital multimeter – used to measure voltage, resistance &. 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. Function testing involves manual or electrical manipulation of components to confirm signal paths and device operation.
