Description

Ashfalls from volcanic eruptions can pose a considerable risk to electric transmission and distribution networks. Dry ash is non-conductive [1] and unlikely to cause an insulator flashover; but it is of concern when the ash becomes damp/wet through light rain, dew, and fog. Volcanic ash is the signature of a volcano; all volcanoes have slightly different volcanic ash. During an eruption the ash absorbs charged halogens and molecules into its surface which dry to become soluble salts [1]. When...
