A computer aided engineering (CAE) system for solving electric field problems is used as an aid in designing of insulators. Since the CAE system has been completely operated on a network of workstations, the use of CAE workstations is very expensive. At this point, we have had the idea of employing a personal computer (PC) for the CAE system, and developed personal CAE software. The personal CAE system is a combination of CAD system, electric field calculation with finite element method (FEM) and data base (DB) of insulating materials. The CAD system consists of a geometric drawing procedure for insulators and a fully automatic meshing procedure for adapting the FEM. The user can graphically draw the design of insulator and electrode arrangements at a PC color monitor with the clicking of a button on a mouse, and obtain the necessary informations for a careful selection of the insulating materials through the DB. In evaluating of proper insulation design, the PC color monitor displays not only electric field distribution but also the tolerance which is a certain percentage of electric field intensity to dielectric breakdown strength of insulating materials. It is concluded that the insulation design is conveniently evaluated by the tolerance for insulation strength.
