Evaluation principle and method of horizontal grounding electrode based on time‐varying impedance
IET Science, Measurement & Technology, 2021 The length of the horizontal grounding electrode is usually extended to decrease the impulse grounding resistance. In this paper, the mechanism for influencing the effective length is revealed by studying the dispersal process of a horizontal electrode ...
