Abstract
The current-votlage characteristics of negative corona discharge with the point-to-plane electrode system were studied. The aim is to introduce temperature and inter-electrodes spacing into the empirical formula “I = A(V — V0)2” that governs these characteristics. It was experimentally demonstrated that the coefficient A of the relation is proportional to temperature and the power of the inter-electrodes spacing independently, and the corona inception voltage V0 is proportional to the power of the inetr-electrodes spacing and is temperature-independent. From these results, a more generalized empirical formula was determined to estimate the discharge current with an accuracy of 10%.
