Circuit breaker secondary injection testing
WebDec 4, 2010 · A secondary injection test, on the other hand, is done by injecting a current with the contacts closed but with no current flowing on the poles. This is a better way of testing circuit breakers because it uses low voltage signals that are injected to the circuit breaker which prolongs the operating life. WebFeb 23, 2024 · The output of the primary injection test set depends on the input voltage. It is essential that the input voltage provided should be within ±5% of the specifications for …
