SLQ 500A 1000A Nanosecond High Current Electrical Pulse Generator

Specifications

Continuous Running Primary Current Injector Tester 5000A Transformer Injector Testing Equipment Why Primary Injection Tests? this type of test involves the entire circuit current transformer primary and secondary Wingdings, relay coils, trip and alarm circuits, and all intervening wiring are checked. There is no need to disturb wiring, which obviates the hazard of open-circuiting current transformers, and there is generally no need for any switching in the current transformer or relay circuits. Typical applications of primary injection testing

Besides the trip test of the complete loop to determine the integrity of the whole secondary protection circuit, other typical primary injection testing applications are:

L Checking that the MV/HV/LV circuit breakers trip in response to an overcurrent.

L Checking of CT/VT/PT ratios and polarities, to determine that the relationship between primary current and secondary current seen by the relay is correct.

L Checking the correct wiring of the protection system, and that all protective devices are properly connected.

L Checking of overcurrent and earth fault relays through primary injection testing.

L Checking of CT circuits, to verify that all switches and protective relays receive the proper current at the proper angle as expected.

L Testing of reclosers and sectionalizers.

L Thermal tests on busbars, switchgear and electrical panels.

L Testing ground grid installations.
