Abstract
This paper analyses the exposure of electric field in the Right of Way (ROW) of 500 kV extra high voltage (EHV) transmission lines, in the presence of Paraserianthes-Falcataria tree. The electric field has been investigated. The computations were carried out using MatLab software by solving the electrostatic equations. The analyses depicts that the magnitude and exposuring of the electric field varies with the height of the Paraserianthes-Falcataria tree in the air-medium that used as its insulation, and then value of the voltage gradient at the top of branch of tree was calculated. The results are of high significance to the insulation of air dielectric strength failure. the results was happened failure air as insulation when the value of voltage gradient on the top branch of the Paraserianthes-Falcataria tree exeeded the air dielec tric strength.
