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 Oil Filtration Machine | Purification plant ... Oil Filtration Equipment (IOT) To handle electrical stresses, transformer oils are required to have better dielectric strength. Lower residual water, gas and contamination content must be maintained to reduce the speed of oil ageing. All of these operations are performed using the transformer oil filtration equipment (IOT).
