Abstract

Utilizing simulation software, this study models the variation in the electric field within the composite insulator crossarm when condensation occurs on its inner surface and examines the effects of moisture intrusion on the internal insulation characteristics of the composite insulator crossarm. The simulation results indicate that droplets on the inner surface of the composite crossarm can cause distortions in the internal electric field, making it more prone to partial discharge phenomena, and may even lead to surface flashover when the droplets are densely packed. In the case of moisture intrusion into the cavity, the condensation alters the insulating state of the inner surface of the composite crossarm, thereby affecting the characteristic quantities of internal flashover voltage and leakage current.
