Answer: The integration of large-scale renewable energy sources has introduced greater variability in power flow, making the real-time performance of overhead lines more critical than ever. This has led to an increased focus on advanced monitoring technologies and operational strategies.

A key trend is the adoption of overhead transmission line monitoring systems to enable dynamic rating. Instead of using static, conservative capacity limits, these systems use real-time data on temperature, wind speed, and current to calculate the actual maximum power a line can carry. At Ningbo Changshi, we provide a complete suite of equipment and tools for the installation and maintenance of these modern monitoring systems, supporting the safe and efficient operation of power grids in the era of renewable energy.
