Abstract:For live detection and training, State Grid Xinjiang Power Company developed a set of live faultiness simulation device. This device featured with fault discharge along surface and many other common fault model. Based on the electric field distribution while fault discharge along surface, this paper discussed the effect of fault parameter on the electric distribution. Fault discharge along surface minimodel was established. Based on research, if voltage boosted to 5kV, DMS ultrahigh frequency partial discharge meter will capture the partial discharge signal; if voltage boosted to 9kV, test model generated corona and typical partial discharge pattern; there will be continuous breakdown if voltage boosted to 27kV. Approximate range of fault parameter was determined. Partial discharge live detection simulating device well performed in research and training.
