New technologies to monitor power lines are emerging worldwide, part of continuing efforts to harden the power grid and increase reliability and resiliency. Utilities and other operators of electricity transmission and distribution (T&D) systems have made T&D upgrades a priority as power outages become more frequent due to an increase in the number of extreme weather events across the world.
Today’s monitoring technology features wireless power line sensors, cameras, and faulted circuit indicators that may use advanced detection algorithms to sense problems on overhead lines in real time.
