ABSTRACT
When the single-phase ground fault occurs in the small current grounding system and grounding current extinguishes after zero out, high voltage will be produced as the recovery voltage more than dielectric insulation strength recovery. After the arc suppression coil is connected to neural point, on the one hand, the single phase grounding capacitive current can be compensated by arc suppression coil inductance current, grounding residual current was decreased; on the other hand, the speed of recovery voltage can be reduced a lot and it is helpful to extinction of fault arc. This study makes certain analysis on the influence of the arc over-voltage when the neutral point is connected to the resistor.
