Some notes on the impulse characteristics of type a grounding of transmission line tower
This paper deals with investigation of the impulse characteristics of transmission line tower grounding. Investigations of the impulse characteristics of transmission lines tower grounding in this paper are based on experimental analysis conducted on type “A” grounding of transmission line tower. Firstly, paper describes the problem of back-flashover and impact of transmission lines tower grounding impedance on it. Also, experimental investigation of impulse characteristics with different rise time of current wave front on real type “A” grounding are given. Finally, detail analysis of experimental data is given.
