This paper presents application of line surge arresters (LSA) on the different voltage level multi circuit overhead lines. Double shielded compact with and without distribution same tower is analyzed. Distribution has lower insulation level, meaning that almost all flashovers will happen circuit. Flashovers help to improve lightning performance transmission circuits. diverts fraction current al...
