Field Measurements of Combined Icing and Wind Loads on Wires,
Abstract
Four winter field seasons of simulated power line icing data were obtained during the years 1977-1981. Measurements were obtained of the icing characteristics, loads on the wire, and wind conditions simultaneously. Loads were measured using a single-axis load cell in line with the wire during the first three seasons, and a tri-axial load cell (resolving three perpendicular force components) in the 1980-81 winter season. Winds were measured using a vaned pitotstatic tube located near one end of the wire. Load records indicated maximum loads in the 400- to 600-kg range (> 50 kg/m) occurred from combined wind and ice loads. Correlations are made with wind speed records to establish drag coefficients for the various ice accretion types observed.
