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.
