Electric Field Calculation on High Voltage Transmission Line – Analysis and Modelling

Abstract

An electric field exists in a region or space if a charge, at rest in that space, encounters an force of electrical origin. The electric field created by high voltage transmission line stretches out from the energized conductors to other conducting objects for example the ground, towers, vegetation, building, vehicles and individuals. Electrical field is theoretically affected by the transmission line voltage, load current, sag above the ground and environment condition. In this project a three-phase overhead transmission line model in different configuration as analyzed for electric field radiating to atmosphere around the transmission line. The electric field line calculated, at different voltage levels in various configuration as helps deciding in the height and ROW for towers.
