CIGRE Canada Study Committees Update Meeting 2021: Advancing Overhead Lines Technology
Study Committee B2 focuses on improving overhead lines technology, ensuring reliability, and environmental compatibility. The Canadian representative, Pierre Van Dyke, plays a key role in Technical Direction and various advisory groups. Working groups within SC B2 address diverse topics such as dynamic line ratings, sustainable conductor solutions, and prevention of equipment corrosion. The collaborative efforts of experts from 48 countries result in technical brochures and project completion dates spanning until 2023.
