Surge Arrester: Minimizing Electric Field Stress in Resistors

From Infolytica Corporation

The voltage distribution along the resistors in a surge arrester is uneven due to stray capacitances. It is possible to reduce the maximum electric field stress by a careful choice of position for the grading rings. In this example, OptiNet is used with ElecNet to find where the rings should be placed, and what their dimensions should be, in order to minimize the total electric field stress in the resistors.
