Computation of electric field and human body induced current under overhead transmission lines

Abstract

In this paper the Charge Simulation Method (CSM) is implemented to compute the electric field distribution around Egyptian three phase 500kV transmission line, with the presence and absence of the human model. The human body is simulated as a conducting cylinder object with a hemisphere for his head. Three positions of human body model are considered to compute the induced current in it. These positions are defined as under maximum, minimum and average conductor heights. A method to estimate the human body model induced current from the electric field computed without the presence of the human body model is proposed and its results are in good agreement with those computed with the presence of human body model under the transmission line.
