چکیده
|
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.
