A Comprehensive Procedure for the Partial Discharge Measurements & Power Frequency Withstand Test on GIS in Transmission Substations

The Transmission part of the power sector is very much important as it deals with huge losses complete sector. substations play a key role in transmission process since generation at plants to final stage consumer end utilization. utmost care should be taken protect these same reduce losses. substation needs protected from blackouts which big problem substations. For this, high voltage equipment’s like GIS & Power Transformers are properly installed energized according standards for its maintenance. So, during commissioning after installation before energization, there different tests performed on equipment’s, especially Gas Insulated Switchgear, High Voltage Partial discharge has impact ageing and life time can easily assessed saved damage, tripping blackout substation. procedure test partial clearly explained this paper.
