Description

This paper investigates the relationship between the charge Qi of the first impulse corona and the associated inception voltage Ui for a 1 m point-plane airgap submitted to impulse voltages. Experimental studies under both polarities are reported; the Qi-Ui characteristics obtained allow empirical quadratic relationships between these two quantities to be derived. A physical interpretation is proposed by considering the established characteristics of the first impulse corona. The Gauss and Ampere-Maxwell laws can be applied and the quadratic Qi-Ui relationship is justified by the present model
