Abstract

It is evaluated that electric shock risk in bath so that we made and designed a bathtub which is the same size in real public bath. And then, we did an experiment, provided of electric leakage in various conditions, so we measured how to form an electric potential and knew the electric potential is formed variously under exposed conductor in bath. Also, we made certain that electric shock risk is down if we insert an insulated pipe in bathtub pipe which is prevent from being formed the electric field sharply. The results show that the increased shock risk and safe distance are estimated by the bathtub of limited width and depth, and the voltage simulated on the basis of Flux 3D concept is compared with the measured value.
