Abstract :
The authors describe how the MSC/MAGNETIC finite-element analysis program is used to compute electrostatic and electrodynamic fields. Example calculations are described for a capacitor with multiple lossy dielectric layers and for a high voltage bushing with a resistive coating. Comparison with classical results is given for the capacitor. The results for the simple lossy capacitor agree with conventional circuit theory. The results for the conductively coated bushing appear to show correctly the influence of conductivity on AC electric fields
