A New Method for Calculation of Corona Inception Voltage in Stranded Conductors of Overhead Transmission Lines

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.
