Current Injection Testing at Roberta Simpson blog

Current Injection Testing. Primary injection testing involves injection of current through the poles of the circuit breaker to verify that the breaker will operate. Primary injection testing is a method used to verify the performance and functionality of protective devices, such as current transformers, relays, and trip units, by injecting a calibrated current directly into the primary side of the This immunity test is carried out by inducing disturbance signals into the wiring harness by means of a current injection probe, as shown in figure 1. Current injection testing is used to simulate a single phase to earth fault by injecting a low power, off frequency current into the earthing system. Standardise and prescribe the method for earth injection testing of a substation earthing system for the purpose of determining current. Primary injection testing involves injecting a high current into the primary side of electrical equipment, such as circuit breakers.
