Numerical Investigation to Determine Corona Inception Electric Field, Using a Rod-plane Configuration

This paper deals with the computer simulation to obtain an empirical equation for field form factors of hemi-spherically capped rod-plane system and determine the range of applicability is done. The obtained data to derive a more accurate equation for calculation of Eincp and Emean has been analysed. Then, the effect of atmospheric pressure and temperature variation on the corona inception voltage by laboratory tests and derive correction factors to standard atmospheric conditions set by IEC are investigated.
