Grounding Resistance Measurement of Transmission Towers in Mountainous Area

Abstract

Due to limitations of 0.618 pole method, the triangle method and the champ ground resistance tester method on grounding resistance measurement of transmission lines and towers under conditions of complex landscape in a mountainous area, it adopts a generalized three-electrode grounding resistance measurement method which arranges electrode flexibly in the grounding resistance measurement of transmission lines and towers under conditions of complex landscape in a mountainous area, and the measurement results of the generalized three-electrode grounding resistance measurement method compares with the measurement results of the 0.618 pole method and the triangle method. Research results show that the tower grounding resistance measurement method based on the generalized three-electrode method is correct and feasible in engineering and it supplies a new method for the overhead transmission line and tower grounding resistance measurement under conditions of complex landscape in a mountainous area. DOI: http://dx.doi.org/10.11591/telkomnika.v11i8.3046
