It is a common partial discharge phenomenon that is provoked by metal spikes on the surface of the high voltage bus bar of the GIS (Gas Insulated Switchgear). To measure the partial discharge based on UHF(Ultra High Frequency) under frequency voltage is also a very common field test project. In orde...
