Short summary
Ice forming on power lines during freezing rain can cause serious damage to electricity networks. To better predict this risk, we studied how supercooled water droplets hit, stick to, and freeze on power lines. Using a new optical measurement method and laboratory experiments, we built a more accurate prediction model. Our results show that icing can be predicted much more reliably, which can help improve early warning and protection of power grids.
