Surge protective device is a part of internal lightning protection and it crucially to divert the certain amount of surges to the ground before the protected load able to handle. Therefore, this paper studying the enhancement of SPD through the effect of adding a filter in hybrid surge protection circuit using simulation modeling. Ordinarily, filter is used as in eliminating noises in certain application such as electronic apparatus. Furthermore, an experiment testing is pursues in high voltage laboratory for comparison and to validate the simulation.
