National Grid is installing technology on its electricity transmission network that has the potential to expand the capacity of its overhead power lines.

Along with LineVision, a provider of non-contact overhead power line monitoring systems, National Grid is installing sensors and a dynamic line rating (DLR) platform on a circuit in Cumbria to increase its power carrying limit.

According to National Grid, the sensors will continuously monitor the transmission lines and apply advanced analytics to calculate the Dynamic Line Rating, which is determined by a power lines physical and electrical properties, including size, resistance and maximum safe operating temperature, plus local weather conditions.
