A Study on the Electrical Characteristics on Contacting the Ground of the Underwater Human Body Model

In this paper, electrical simulations of electric shock accidents at voltages of 220V have been carried out using an Andred s body model underwater. First, we construct a circuit fitting Andred s body model. Then, we compare voltage measurementsat a hand, breast, and the waist, and current measurementsat the same locations, with safety limits of electric current flowing through a body. We conclude from our results that the magnitude and wave of an electric currentpassing through a body mimics the effect ofa heart control signal. It also hasa direct impact on the ventricle of the heart in detailed motion. The simulations have been performed with the ATP-Draw program. Furthermore, this study finds safety issues for an electric angle limit when taking measurements of a flooded body resistance, and the voltage and current passing through each part.
