چکیده
From a field-theoretical approach, it has been possible to develop a physically valid theory of partial discharge transients. Thetheoryis baseduponthe concept of the charge induced upon the detecting electrode by the partial discharge. This induced charge is shown tobe composedo f a componentassociated withtheactual spacecharge inthevoid, and one related to changes in the bulk po la r i za t ionbrough tabou tbychanges in the field external to the void due to this space charge. The magnitude of the induced charge and its components are discussedinrelat iontoaheterogeneous bulk dielectric system.

متن کاملThe Functional Relation between Partial Discharges and Induced Charge
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...
متن کاملDielectric Response and Partial Discharge Diagnostics of Insulation Systems by Utilizing High Voltage Impulses
In this thesis, power system transients are considered as an opportunity for development of online diagnostics of power components and specifically the insulation systems of power transformers and bushings. Failures of power components and outages can lead to a huge economical loss in the electric power grid. Therefore reliable operation of power grid requires on-line monitoring and diagnostics...

Abstract – In this paper, the effect of applied electric field on the damage due to partial discharges activity into the surroundings dielectrics of a narrow channel encapsulated within the volume of a dielectric material is evaluated using a kinetic model based on Particle in Cell - Monte Carlo Collision (PIC-MCC) model. After application of an electric field across a dielectric material which...
