Topology optimization for a station class surge arrester model
International journal of numerical modelling, 2022 High‐voltage stress can cause partial discharges, which in turn result in deterioration of high‐voltage equipment, and hence, in increased maintenance costs. To this end, corona rings are used as means to capacitive field‐grading.
