| Abstract: | In order to solve the problem of substation grounding impedance measurement with lightning line connecting, a kind of accurate grounding impedance measuring method for the grounding device was established in the partial power lines failure conditions in this paper. The current sensor with wireless remote measurement was developed to test the lightning line shunt current. The auxiliary grounding pole was fixed by GPS positioning device. Finally, field verification test of the method was carried out in a 500 kV substation, and results showed that the method can satisfy the requirement of engineering operation. |
