Thermal analysis of H.V. insulation oil during partial discharge detection

Historically, the arc discharge analyzing technique was one of the first methods to determine the status of the insulation oil. Due to the harsh environment and the continue usage of the high voltage transformers, many problems of insulation can be produced leading to the failure of the transformer....
