Ieee draft guide for forecast and early warning of icing on overhead transmission lines in micro-topographic areas

This guide is applicable to the prediction and early warning of icing on overhead transmission lines (OHLs) in micro-topographic areas, presenting criteria for identifying micro topographic areas and methods for predicting the icing thickness of OHLs. This guide aims to provide guidelines for the observation, monitoring, prediction, early warning, and melting of ice on OHLs in micro-topographic areas, serving as references for anti-icing design and maintenance of OHLs in icing prone areas.
