WebbA 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. WebbTEST 2 – No Delay Trip On Upstream Breakers (Normally mains and ties) Verify that each upstream breaker will trip with no time delay (minimum setting 0.1), when not receiving a restraint signal from a downstream breaker. Push test pushbutton and release to start the test. The breaker should trip without any time delay (minimum setting 0.1).
