  1. The problem about neutral - point - grounding mode is an all - around technical problem which associated with not only power system reliability ， insulation coordination ， electromagnetic interference ， but assault safety 。 in china ， the neutral grounding modes of the 10kv net involved of none grounding, grounding by arc suppressing coils, resistance grounding or reactance grounding in the past 。 with the development of civic power network ， low resistance grounding mode was used to restrain the over voltage, particularly in guangzhou, shanghai ， beijing ， and zhuhai etc. it was reported that the over - voltage level of low resistance grounding mode is lower than that of arc suppressing coil mode, but the operation carried out the other way 。 at substations in guangzhou and shanghai it was found that the low resistance grounding mode is successful 。 but in some areas ， such as zhuhai ， substations grounding with low resistance revealed some problems ， including power supply reliability rapidly dropping ， transmitting line often tripping ； and person safety being threatened 。 so interiorly the grounding mode selection of the 10kv network was disputed, which mainly focused on the fault form of 10kv net grounding, the apply area of suppressing arcing coil grounding mode, power supply reliability level of the two modes, person safety, communication interfere and the workload of maintenance
