Application of Arcing Suppression Coil with Parallel Resistance in Urban Distribution Networks Earthing

The arcing coil grounding mode and the resistance grounding mode of neutral point in urban distribution network are analyzed,and the mode of arcing coil with parallel resistance grounding through working experience is provided. Its theory and implementing method are also introduced. This new grounding mode combines the advantages of arcing coil grounding and resistance grounding,and it would be able to provide useful references to the grounding mode of neutral point.
