Discharge Detection

Gas insulated switchgears occupy an important position in the power system. But the partial discharge would occur because of insulation defect, PD will lead to the GIS insulation damage after a long time, and will lead to serious consequences without treatment in time, therefore, the PD detection is particularly important. PD is detected by its secondary physical phenomena, including the phenomena of sound, light, electromagnetic waves and gas decomposition products and so on. At present, many scholars in China and foreign countries have done a comprehensive study on insulation detection technology of GIS and have achieved a large number of results. The author do a detailed overview on the detection technical of GIS insulation state, including GIS platform and the simulation of typical insulation defectspartial discharge detection methods, SF6 alternative gas and pattern recognition. These works provide a valuable reference for follow-up study of GIS.
