This paper addresses the localization of Partial Discharge through a 3D Finite Element Method analysis acoustic wave propagation inside 3-phase 35kV transformer with help COMSOL Multiphysics software. Due to complexity transformers, waves generated by PDs cannot simply be detected typical sensors, especially when happen inner windings. These are distorted and attenuated along their propagation....

Analytical expressions are deduced for the quantitative evaluation of the charge induced on an electrode by a partial discharge (PD) within a dielectric body. Two approaches have been employed to effect this evaluation. These are characterized by the X function and the $ function, and the essential relationships to be fulfilled by X and q5 are derived. The principal difference between these fun...
