Influence of earthing resistance on the performance of distribution line lightning arrester

The line lightning performance of the 33 kV distribution line Tanjung Batu - Rompin gives very bad performance during lightning. The lines have bad performance although they were equipped with the line lightning arrester to limit the overvoltages on the phase conductors when lightning strikes the line. There are several cases where the surge arresters were broken and exploded. In this study, the effect of earthing resistance on the surge arrester was studied and simulated using ATP-EMTP to determine the performance of the line lightning arrester in limiting the lightning voltages on the phase conductor.
