Abstract

In this paper, a method for measuring the grounding resistance of the tower without disconnecting all the down conductors is proposed for the first time in view of the shortage of manual measurement of the grounding resistance of the tower. This paper introduces the measurement model of single or multiple down conductors, and uses a hybrid genetic algorithm to comprehensively calculate the grounding resistance of all towers in the closed loop, which greatly improves the measurement accuracy. Through simulation analysis and actual measurement, it proves that the method is simple and convenient to measure, does not need to disconnect the grounding wire, and has high measurement accuracy. Compared with the clamp ammeter method, the accuracy is improved by 30%. The method is applied to the on-line monitoring system of the tower grounding resistance, which can reduce the labor intensity of the line maintenance personnel, greatly improve the work efficiency and provide a basis for discovering the fault in time.
