| Abstract: | In this paper,according to the failure of the electroscope,the working principle and influence factors of the capacitance electroscope for 220kV transmission line are studied.The impact of the starting voltage by the fittings, separated number of sub-conductor and angle between the electroscope and the conductor are analyzed through simulation.By the result of the simulation,the electroscope and used it on 220kV transmission line under different condition is modified,which could solve the failure of the electroscope,and this can assure the safety of the workers. |
