Abstract

The integrated grounding system which bundles up all various grounding electrodes has been introduced as a new grounding system from the movement toward the formation of standard international adjustment in recent years, and the example adopted also in high voltage receipt equipment is increasing. However, there are very many differences between TN system in the West and TT system in our country and points to be checked since the grounding purpose is crossing variably as the account of the upper stated, when adopting an integrated grounding system, and there are few examples checked experimentally until now. In this research, the viewpoint was extracted to lightning protection in such a background, the grounding system and integrated grounding system which were used with high voltage receipt equipment until now were compared, and real experiment and EMTP analysis were carried out for the purpose of grasping the characteristic in an integrated grounding system. From the experiment result in high voltage receipt equipment, and an analysis result, the result verified about the usefulness of integrated grounding to lightning protection is reported.
