LineWatch Supports Canada's Largest Utility with Voltage-Based Fault Detection

QinetiQ North America has received an order from Hydro-Québec in Montreal, Canada, following a successful pilot program, for LineWatch L power line sensing and monitoring devices developed by QNA. LineWatch-L sensors provide a unique set of highly accurate data measurements in support of the HQ MILE voltage-based fault detection algorithm. LineWatch-L /MILE provide power utilities greatly improved fault detection and location for more efficient and faster maintenance and restoration, all while using less deployed equipment at a lower total cost.

LineWatch-L is one of a family of LineWatch products specifically designed to enable more cost effective grid operations. LineWatch L provide high accuracy (+/- 0.5%) voltage and current measurements and enable a number of grid modernization applications including fault detection, substation monitoring, asset management, volt/VAR optimization and power diversion detection. The LineWatch Low and Medium Voltage sensors were introduced in February 2015 at the annual DistribuTECH Conference & Exhibition held in San Diego, Calif.

Mark Federle, director of Smart Grid Solutions at QinetiQ, said, "We have worked closely with HQ to enhance our LineWatch L product to enable the HQ MILE functionality. This order represents the next step in a larger initiative to deploy the MILE voltage based fault detection system within the HQ distribution network as well as market it to other utilities challenged by the same transient fault issues. We believe this system will dramatically change the way utilities instrument the grid for fault detection and we are excited to be working with HQ on this very innovative approach to address this industry wide challenge."
