1.9 Manual Breaker Injection
The Manual Breaker Injection feature allows the operator to inject currents and voltages without
knowledge of the Switchgear configuration.
Operators must enter the configuration of the circuit breaker under test and must calculate the
levels required to generate the expected trip conditions.
NOTE: This feature is for the advanced operator who knows the configuration of the circuit
breaker under test, and knows what levels to inject to test the desired protection functions.
