Choice of Electrical Field Calculation Method According to the Dielectric Design Criteria

The use of simulation programs has given high security and confidence in predicting and investigating the performance of transformer insulation systems. Two most commonly used methods for electrical field calculation are finite element method and boundary element method. Each of the two methods has its advantages, depending on the applied dielectric design criteria. In this paper both methods will be analyzed and presented on real case study of power transformer main insulation. Maximum and cumulative design criterion will be applied in order to conclude which method and criterion combination provides adequate results.
