| Abstract: | There is greater influence of HV overhead lightning conductor on measurement results of grounding impedance for grounding network. The measurement results of grounding impedance are larger in opening the HV overhead lightning conductor than that before the opening. Two measurement methods and their wiring principles, line 0.618 and 4 poles, were introduced. The influence condition of 110 kV overhead lightning conductor with T type connection on measurement results of grounding impedance for grounding network in Baizhangji Hydropower plant were also introduced. |
