Line Surge Arresters Applications On The Multi Circuit Overhead Lines

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 along its phase conductors, improving at time coupling between All software simulations are performed using sigma slp package. A short description modeling for flashover rate determination given. In order prevent LSA installed this only. The improvement in similar obtained LSA. much cheaper than
