| Abstract: | Along with the increase of capacitive current in isolated neutral system,arc grounding over-vohage and phase to phase fault easily occurs in power system which could be quite damaging to power devices. This paper analyzes the cause of grounding switch damage, establishes a mathematical model, and proposes the suppressing measures. The correctness of eonclusions from the theoretical analysis is verified by Matlab/Simulink. |
