Abstract
The paper deals with the numerical simulation of transient fields using Boundary-Element-Method (BEM) and Discrete Fourier Transformation (DFT). Instead of solving the Maxwell equations for transient fields in the time domain a numerical method using the DFT algorithm for solving in the frequency domain is developed. Impulse voltages and polarity reversal for HVDC systems are simulated as examples for the transient stresses. The application example is a standard spacer for Gas Insulated Substation (GIS) used in 145 kV systems. Investigations are made concerning the sampling rate and frequency. The behavior of conductive and non-conductive spacer surfaces due to transient fields are made. Furthermore for the calculations a parallel numerical solver based on PVM (Parallel Virtual Machine) is used. Results are proving the advantage of this tool to reduce the calculation time.
