【Abstract】 Metal oxide surge arresters are installed on transmission lines where tower grounding resistance is high and conventional means to lower tower grounding resistance are not practical. The paper investigates characteristics of some tower and transmission line models developed by the Alternative Transient Program (ATP) in order to simulate the lightning performance of a 110 kV transmission line. The results obtained from simulation can help to determine the countermeasure to reduce lightning faults in the transmission line by installing transmission line arresters with series air gap.更多还原
