Abstract

A physically valid theory of partial discharge transients has been developed through a field theoretical approach. The theory is based upon the concept of the charge induced upon the detecting electrode by the partial discharge. This induced charge consists of a component associated with the actual space charge in the void, and one related to changes in the polarization of the bulk dielectric. The latter is brought about by changes in the field external to the void due to the void space charge. The magnitude of the induced charge and its components are discussed with reference to a coaxial, heterogeneous dielectric-system
