Notes:
As the number of delicate semiconductor devices in the electric equipment increases, it isalso getting more important to prohibit the surge wave from intruding the equipment. The bettersurge-wave protection can be achieved when we reduce the earth resistance further in the earthingsystem. It is practically best, however, to set an appropriate value of earth resistance if we consider thecost and effort required to install the earthing system. In this work, we demonstrated an example ofextracting an optimized earth resistance by using a simulator that theoretically predicts the evolutionof discharge current of the earthing system. The measure discharge currents of the real earthingsystem with the optimum earth resistance has confirmed that our method was efficient and useful
