Influence of Void Geometry and Bulk Dielectric Polarization Upon PD Transients
Through a field-theoretical approach, a physically valid theory of partial discharge transients has been developed. the theory is based upon the concept of the charge induced upon the detecting electrode by the partial discharge. Mathematically, this induced charge is composed of a component associated with the actual space charge in the void, and one related to changes in the bulk dielectric polarization brought about by the space charge.
