Tech: Purpose of Secondary Current Injection Test, Sequence to do Primary Injection Test and Secondary Injection Test
Secondary injection tests are always done prior to primary injection tests. The purpose of secondary injection testing is to prove the correct operation of the protection scheme that is downstream from the inputs to the protection relay(s). Why done prior to primary injection tests? This is because the risks during initial testing to the LV side of the equipment under test are minimized.
The primary (HV) side of the equipment is disconnected, so that no damage can occur. These tests and the equipment necessary to perform them are generally described in the manufacturer’s manuals for the relays.
