Modelling of Surface Charge Decay in a Spherical Cavity within a Solid Dielectric Material Using Finite Element Analysis
نویسندگان
چکیده
The modelling of cavity surface charge decay through conduction along the cavity wall using the Finite Element Analysis (FEA) method is presented in this paper. A field-dependent cavity surface conductivity is proposed and the Phase-Resolved Partial Discharge (PRPD) patterns obtained from experimental measurements used to validate the simulation results generated using the model. A comparison between the simulation and measurement results has also been undertaken to verify the surface charge decay effect.
