| Abstract: | In the paper, a new principle of automatic resonantarc-suppressing coil is proposed, which produces no harmonics and automatically compensates the grounding capacity current with rapid response in a wide range. Its main part is a continuously adjustable high power reactor based on controllable magnetic flux. The method of frequency scan is used to detect grounding capacity. Their principles are analyzed in detail, and the way to realize automatic resonant of the adjustable reactor and grounding capacity is explained when the single -phase earth fault occurs. The principles and methods are proved by experiment results of a prototype. |
