After analyzing the current state and existing problems of automatic resonance arc suppression coil, this paper proposes a new type of arc suppression coil with thyristor series capacitors (TSC). Its principle and design method are described. The results of theoretical analysis and field testing show that the coil features high response speed, wide adjusting range, fine linearity of volt-ampere characteristics, etc. The automatic resonance neutral grounding apparatus using this coil can measure accurately the capacitive current in single-phase to earth fault and provide optimal compensation. It has good application prospect.
