New controlled switching approach for limitation of transmission line switching overvoltages
In this study, a new controlled switching approach is proposed. This method is applied to the controlled closing of high voltage uncompensated transmission lines. The new approach is a developed version of conventional zero‐crossing controlled switching approach. Performance of the new approach is evaluated and compared with the conventional controlled
