Wet Snow Icing-Analysis of Field Measurements 1999-2016
Wet snow icing accumulation on overhead power lines is rare in most countries.Experience has shown that the frequency and quantity of wet snow accumulation is high in Iceland,but it is very site-dependent and can vary greatly between areas and locations.This paper presents analysis of field measurements of wet snow icing at 10 locations in Iceland from 1999 to 2016.Measurements are made of both operating power lines and specially erected test spans/lines to measure icing.Discussion and classification are made on the main topographical conditions where the most extreme wet snow icing has been occurring.Large-scale effects and the effects of local topography explain the variation.Measurements are presented of accumulation on conductors of different diameters.
