Abstract

This study performed an experiment for the danger of an electric shock in the human body, which is directly touched or approached to the exposure of buried metals in a leak caused by certain ground faults at a buried cable in street lamp. In the results of the experiment, the dangerous of electric shocks due to the earth specific resistance and wet and submersion of the earth surface represents a high level as the human body is directly touched to the buried metal at a leak point. In addition, it can be seen that the safety of the human body is influenced by the earth specific resistance, separated distance from buried metals, and shape of buried metals at around the leak point.
