The primary challenges in maintaining overhead transmission lines include:

• Aging Infrastructure: Many grids worldwide are aging and require modernization.

• Environmental Factors: Extreme weather, such as storms and icing, can cause significant damage.

• Safety and Efficiency: Traditional maintenance methods often require power shutdowns, which are costly and inconvenient.

To overcome these challenges, the industry is adopting innovative solutions. Live-line maintenance techniques, like the bare-hand method, allow crews to work on energized lines, minimizing service disruptions. Additionally, predictive maintenance powered by smart grid technologies, sensors, and drone inspections with LiDAR and thermal imaging cameras, enables early detection of potential failures, shifting the focus from reactive repairs to proactive management.
