When these tests are performed at a factory or repair facility, current is injected into all three poles of a circuit breaker simultaneously.Primary vs. Secondary Injection Testing fA primary injection test set injects a multiple of the fault rated current of the breaker, through the breaker while measuring the trip time. The secondary injection test injects a ratio of the fault rated current of the breaker directly into the trip unit and measures how long it takes the breaker to trip.Primary & Secondary Injection Test Sets 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 Requirements (FeedbackPeople also askCan primary and secondary injection testing test circuit breakers?Primary and secondary injection testing can both test circuit breakers, but they have unique applications.

For testing a low voltage circuit breaker with primary injection, the current is injected through the circuit breaker MeggerODEN AT primary current injection test system | MeggerWEBYou may perform up to four primary injection test types to verify that the LVCB is working correctly: a long time test, short time test, instantaneous test, and earth/ground fault test. The long, short, and ground fault tests all have a delay component. In contrast, the instantaneous test trips the circuit breaker immediately.MeggerSmart primary injection test system | SPI225 - MeggerWEBThe SPI225 is a high current primary injection test system for all forms of high current testing required in a substation, including testing overcurrent relays, circuit breakers, motor overloads, and current transformers.
