Abstract

This study aims to investigate the impact of various micro-meteorological factors on the type and quantity of ice accretion on overhead transmission lines through experimental analysis. In an artificial climate laboratory, meticulously designed experimental setups were employed to simulate ice accretion under diverse geographical and meteorological conditions. The experimental results reveal that temperature is a key influencing factor on the type of ice accretion on transmission lines, with higher densities of glaze ice forming near zero degrees Celsius, while lower temperatures favor the formation of lighter rime ice. Additionally, wind speed exhibits a significant influence on ice type, with higher wind speeds favoring the formation of denser glaze ice. Experimental investigations into ice accumulation indicate that the amount of ice accretion on transmission lines increases with higher wind speeds, median volume diameter of supercooled water droplets, and liquid water content, but decreases with rising ambient temperatures.
