Predicting Ice and Snow Loads for Transmission Line Design,
Abstract
A methodology is proposed to transform standard meteorological data into probability-based transmission structure loads at any location within the Pennsylvania Power and Light Company's service area. Proposed accretion models are presented for estimating ice and snow accumulation on transmission line conductors using standard weather station data. The results are synthesized and subjected to extreme value analysis to yield return period versus ice or snow loading relationships. A methodology for combining wind and snow events to predict peak transverse loads is described. The paper focuses on the application of icing models and describes the techniques and assumptions required to institute a probability-based ice and snow load criteria. (Author)
