| Abstract: | In the 66 kV system of a 220 kV substation, the neutral point without arc suppression coil puts pressure on bus bar, which produces resonance. Then the TV insulation got damaged, and the TV explosion caused the bus power outage in next early morning. In this paper, through the analysis of the fault oscillograph, the transient process is restore in detail, and how the resonance occurred and causes of the resonance is analyzed. |
