Building a robust and smart power grid has become an urgent need. Monitoring transmission lines and obtaining real-time information on their various operating parameters is a prerequisite for condition-based maintenance of power equipment and an important component of building a smart grid. Most transmission and distribution equipment is located in remote areas with harsh working environments. When overhead power lines are in operation, there are challenges in monitoring safe distances from the ground, trees, and buildings. In situations where conductors are covered in snow or ice, the safe distance from the ground, trees, or buildings changes. If the conductors sag further beyond the safe distance, the possibility of contact between the transmission lines and the ground, trees, or buildings increases, potentially leading to short circuits or conductor breakage due to the pull of trees or buildings.
