In this paper a new method for onset voltages calculation of negative and positive corona are presented. This method is based on considering electric field and pressure in adjacent of the surface of conductors. This algorithm is simulated for different pressure and radius of conductors. The configuration of conductors are considered stranded as like as overhead high transmission lines. The calculated onset voltages which are obtained by this method agree with primary experimental measured values by researchers.
