PV Magazine – Product Roundup: LineVision AAR+

Sensor for grid reliability

LineVision Inc., a provider of non-contact overhead power line sensor solutions, has launched a line rating offering to help utilities comply with rules proposed by the Federal Energy Regulatory Commission (FERC). LineVision claimed its new LineRate AAR+ provides utilities with a scalable, turnkey solution for FERC compliance while enhancing grid reliability by reducing the times when traditional Ambient Adjusted Rating (AAR) methods would inaccurately overestimate line ratings.

LineVision said these methods can increase line ratings, reduce grid congestion, and enable renewable energy integration. The company’s solutions directly monitor the sag and temperature of the conductors and are powered by Velodyne LiDAR sensors, the same technology used in autonomous vehicles. More info available here.
