| Abstract: | Small current grounding systems are applied widely in 3.3~66 kV power system for the advantage of reliable power supply.In the paper,the feature when the single-phase grounding fault happens is analyzed.The advantages and disadvantages of three types of ground mode are discussed.Schemes adding arc extinction,over-voltage and electrification protection are proposed for the safety potential caused by that the fault can't located in small current grounding systems.The Schemes are proved to be practical and eco... |
