Switchgear Testing and Commissioning Procedure ...· High Voltage Testing Procedure. High voltage test is done by applying 80% of factory-tested voltage. While doing the HV test the steps to be followed are as below: Short all CTs circuits. Isolate all VTs. All the CBs are made into service. For doing 'R' phase the other phases are shorted and earthed. Before HV IR test 5kV megger is to be done.

Transformer Protection and Transformer Fault | Electrical4U· So the transformer protection schemes are very much required. The short circuit current of an electrical transformer is normally limited by its reactance and for low reactance, the value of short circuit current may be excessively high. The duration of external short circuits which a transformer can sustain without damage as given in BSS 171:1936.
