Primary & Secondary Injection Test Sets | Breaker Testing

A 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 injection testing of protection system for wiring

Dec 13, 2017· Primary injection testing is, however, the only way to prove correct installation and operation of the whole of a protection scheme. Primary injection tests are always carried out after secondary injection tests , to ensure that problems are limited to the VTs and CTs involved, plus associated wiring, all other equipment in the protection scheme having been proven satisfactory from

Primary vs. Secondary Injection Testing for Circuit Breakers

Mar 14, 2017· Circuit breakers equipped with solid-state trip devices can be tested using secondary current injection, which requires less time and expense to perform the test. Primary current testing is conducted by injecting a programmed sequence of overload and fault magnitude currents through a circuit breaker and documenting how long it takes the trip unit to activate. When these tests are
