| Abstract: |
over voltages due to switching or lightning may cause damage for the transmission line insulators, transformers and switchgear. The flow of overvoltage to earth through transmission system towers causes an increase in the potential of metal structure and the earth potential and may create back flashover voltage causing failure to transmission system insulators in which transmission line outages occur. In this paper the effect of tower grounding surge impedance on the back flashover is investigated. The coupling factors between the shielding wires and the healthy conductors are considered. |
