Electric field analysis of 66 kV and 110 kV SiR insulators under combined AC–DC voltages

Insulators are the most crucial part of power systems. The insulation performance of insulators is vital for the sustainability of power systems. Recently, silicone rubber (SiR) insulators are used frequently in all sections of the power systems. In this paper, a SiR insulator currently used in powe...
