1. GIS surge arrester was tested by injecting nominal voltage injection during HV test
2.In 380 kV GIS the single phase nominal voltage 220kV was injected in Surge Arrester Through bus.
3. The leakage current mili amps measurement was measured in surge counter and Multi meter.
4. There by the paper connections are conformed.
5. Some cause the outgoing cable bus link and Surge arrester link will be same. So arrester should dismantle separately and Tan Delta test should contact on the table.
