Insulation Fault Caused by Current Transformer Seal Failure

Insulation Fault Caused by Current Transformer Seal Failure

Firstly, the insulation structures of oil-immersed current transformer (TA) and SF6 TA are introduced. And then, the causes of TA insulation breakdowns are analyzed based on an investigation of the insulation faults of TAs occurring in several cases. It is concluded through further disintegration ex...
