Abstract

The efficient indirect boundary-element method is applied to the calculation of 3-D electric fields in high-voltage devices. For solving this problem with sophisticated boundary conditions and with dielectric media, the authors adopt real surface elements, a fast and accurate computation approach, and thin-layer medium treatment. Numerical results are given to verify the efficiency of the program and the accuracy of the calculation. It is noted that the computer program based on the efficient boundary-element method is an important tool for transformer insulation design. It has been used to identify regions of high field strength where electrical breakdown might occur
