Abstract :
This paper deals with the measurement of AC corona inception voltage, Vincp, atthe tip of a rod electrode using a hemispherically-capped rod-plane electrode configurationfor various rod radii with a short air gap. Effects of atmospheric pressure and temperaturevariation on Vincp are investigated experimentally. An empirical equation for the field form factors of the hemispherically capped rod-plane electrodes is proposed with its range ofapplicability. The obtained results are analyzed to derive a more accurate analytical equation for the calculation of the electric field at corona inception voltage, Eincp, and theaverage of electric field distribution, Emean.
