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.
Things to know before purchasing a power transformer· The power rating of a transformer is the product of current and maximum operating voltage. Every transformer with a rating of more than (2MVA) is a power transformer. They usually operate at high voltages, and since every transformer is expected to work at maximum of its capacity you need to ensure the higher power rating of the transformer.
