Effect of earthing enhancing compound (EEC) on improving tower footing resistance of a 500 kV tower in a rocky area
This paper presents a comparative analysis of different earthing designs� performances, with particular interest on the use of earthing enhancing compound (EEC) for a selected earthing design of 500 kV transmission towers in a rocky soil, using the SESCAD tool of the Current distribu-tion, electroma...
