A time-filtering method for plasma simulation: High bulk conductivity

A numerical filter is introduced that enables the simulation of longer time increments using realistic representations of electrical components that include semi-conductive layers.

Numerical simulation is becoming a fundamental tool for predicting the aging of dielectric materials used in industry. In particular, one of the main aging mechanisms, at least as regards alternating current, is represented by partial discharges. For this reason it is important to develop technologies to simulate internal discharges in real, or at least realistic, geometries, which can be very complex. Different materials are present in electrical components and these include semiconductive materials, which are characterized by a relatively high electrical conductivity when compared to the conductivity of insulating materials. The different conductivity leads to numerical problems which, in turn, place limits on the maximum permissible time increase. A numerical filter is applied to simulate realistic components using sufficiently long time increments. An analysis was introduced that demonstrates that the use of the filter enables the use of larger time intervals without compromising the accuracy of the method. This analysis is supported by experimental evidence.
