Modeling and simulation of internal Partial Discharges in solid dielectrics under variable applied frequencies
Partial Discharges PD are events that must be regarded in order to avoid many problems with high voltage equipments. There are different types of discharges and different factors that affect the nature of these discharges that will be discussed in this paper. In addition, analysis of the PD modelling is included. Frequency dependence of PD is included and the effect of some time constants on PD magnitude and number of PDs per cycle is discussed. In addition, a developed model is established in order to study the effect of applying higher frequency on the behaviour of PDs. The magnitude of frequency of the applied voltage was studied as well as cavity size and location in the dielectric. The model can be used to study samples of different types of dielectrics and a complete H.V. equipment can be investigated.
