Arc-suppression coils have such problems as big error in capacitive current measuring and excessive tuning.By analyzing the problems
it is found that weaker input signal of mutual inductor results in the error in capacitive current measuring
therefore a method of increasing amplitude of neutral voltage is presented to improve capacitive current measuring accuracy.Moreover
some methods are also proposed to solve the excessive tuning problem.Experiment and field operation show that these methods can improve capacitive current measuring accuracy and reduce tuning operations
thus enhancing performance and reliability of automatic arc-suppression coils.
