Effects of insulator profile on the critical condition of AC arc propagation on ice-covered insulators

The critical conditions of AC arc propagation on the surface of ice accumulated on 2 types of industrial station post insulators are investigated. The effects of the air gap length as well as the insulator length and diameter on the critical arc maintenance conditions were determined and analyzed. T...

Description
Summary:The critical conditions of AC arc propagation on the surface of ice accumulated on 2 types of industrial station post insulators are investigated. The effects of the air gap length as well as the insulator length and diameter on the critical arc maintenance conditions were determined and analyzed. The obtained results are essential to complete the mathematical flashover model, developed in our previous work, for its further application to long ice-covered insulators.
