Surface charge migration and dc surface flashover of surface-modified epoxy-based insulators
TL;DR: In this paper, the effect of direct fluorination on surface charge migration and flashover voltage was verified, and it was shown that the surface charge decay of epoxy-based model insulators is a slow process, but the decay rate increases when an outer dc electric field is applied.
