Surface charge accumulation of post insulator: Dominant charge transition under different conditions
Publikováno v:
High Voltage, Vol 8, Iss 6, Pp 1225-1233 (2023)
Abstract An insulator surface charge may be responsible for flashover along the insulator surface. In this study, experimental investigations of post insulator surface charge are performed using a variety of voltage, gas type, and gas pressure condit

Air gap defects inside a spacer reduce its insulation performance, resulting in stress concentration, partial discharge, and even flashover. If such gap defects are located at the interface between the insulation and conductor, a decrease in mechanic

Substantial energy dissipation in arc discharge results in strong wall and electrode erosion in a circuit breaker chamber, which largely alters arc plasma properties and thus affects the arc behaviors. Due to the strong vaporization rate, the generat
