High Voltage Transmission Lines: Importance Maintenance and Risks

By increasing population of the world towns are expanding many buildings construct near high voltage overhead power transmission lines. The increase of power demand has increased the need for transmitting huge amount of power over long distances. Large transmission lines configurations with high voltage and current levels generate large values of electric and magnetic fields stresses which affect the human being and the nearby objects located at ground surfaces. This needs to be investigating the effects of electromagnetic fields near the transmission lines on human health. In this concern the electricity system produces extremely low frequency electromagnetic field which comes under Non ionizing radiations which can cause health effects.
