This paper deals with the measurement of AC corona inception voltage, Vincp, at
the tip of a rod electrode using a hemispherically-capped rod-plane electrode configuration
for various rod radii with a short air gap. Effects of atmospheric pressure and temperature
variation 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 of
applicability. 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 the
average of electric field distribution, Emean
