Estimation of New Weighted Controlled Switching Overvoltage by RBFN Model [PDF]
Journal of Operation and Automation in Power Engineering, 2020 Mitigating switching overvoltages (SOVs) and conducting well-suited insulation coordination for handling stresses are very important in UHV transmission Lines. The best strategy in the absence of arresters is controlled switching (CS). Although elaborate
