Electromagnetic Effect of High Voltage Transmission Lines on Human Being

Abstract

Once ignored electromagnetic field have become too hazardous in recent days due to the rampant rise of gadgets which are source of electromagnetic radiations such as mobile phones, power transmission lines and other such devices. This paper put forward a detailed model of electromagnetic field generating because of HV power lines with the use of technique of finite element method so that an idea on the physiological effects of electromagnetic field (EMF) generated by the HV power transmission lines are made available in the public domain. Because it is high time people should know safe limits for electromagnetic fields. The magnetic field and electric field around a HV 220 kV electrical overhead line is analyzed for various geographical regions like agricultural land, coastal land and sandy soil. Two other models of 132 kV and 400 kV are also analyzed. All these analysis are done in presence of human being so as to include the proximity effect. And report so generated is compared with existing guidelines and some new safety measures are introduced too. All the above discussed analyses are done with ANSYS Maxwell 3D. This method is a useful tool for the evaluation of the biological effects and safety standards of high voltage transmission line.
