National Grid trial adds more renewable electricity into 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.

In a statement, Lydia Ogilvie, director of Network Strategy and Operations for National Grid said: “To meet the increasing demand for electricity and deliver net zero, our network needs to grow, but at the same time we are continually looking at ways of expanding capacity on our existing infrastructure… National Grid is leading the way in using transformational and innovative engineering, integrating vital grid enhancing technologies like LineVision’s, to decarbonise and deliver world class reliability, at lowest costs for consumers.”
