About Primary Current Injection Test Sets
A primary injection test is a system that incorporates the current sensors, wiring, and conduction route in the circuit breaker with the test.
A primary injection test is helpful for substations or circuits with high voltage and current. It is just the flow of rated current in the circuit under test. If the rated current of the circuit is 2000 A, then 2000 A of current must flow through the circuit. This is necessary to verify overall equipment health and protection system performance.
Primary injection testing, as opposed to the secondary injection test, is the only way to prove correct installation and operation of the whole protection chain, as the test involves the entire circuit: current transformer primary and secondary windings, relays, trip and alarm circuits, circuit breakers, and all wiring. Primary injection testing is performed during the commissioning and maintenance process, or after any modification, as a functional test of the entire system.
