This paper describes the development of three‐dimensional electric field analysis by using the so‐called segment method which enables the electric field to be calculated with high accuracy and with enhanced efficiency, for high‐voltage apparatus. In the segment method, electrode configuration of high‐voltage apparatus is simulated by small components which are called segments and by the arrangement of several kinds of such segments. In this calculation, the charge simulation method is used which is suitable for segment application. As basic segments, spherical, cylindrical and ring segments are used and in addition to these, as subsegments, disc and elbow segments are adopted for good simulation of the total electrode configuration. In this paper, the fundamental construction and arrangement parameter of segments were discussed. Moreover, the segment method was applied to an actual high‐voltage apparatus and the calculation accuracy was discussed. It was clarified that the segment method has sufficient calculation accuracy and is a very efficient means for three‐dimensional electric field analysis.
