Case studies
Glitre Nett transmits electricity to 210 300 grid customers in Agder, making it Norway's fourth largest grid company. Glitre Nett owns and has operational responsibility for the power grid in Agder.
Glitre Nett (AEN) has about 5 000 km of high voltage (HV) power grid, and they are mandated by law to inspect the entire grid annually. For this they require oblique pictures of the poles, right of way pictures (ROW), nadir pictures of the lines and complete LiDAR scanning of the lines for vegetation management.
Over the last three years, STELLAIRE has collected, analyzed, and presented data for over 105 000 poles on AEN’s power grid. The data collection has exclusively been done with unmanned aircrafts (UAV) and sensor payloads developed and produced by STELLAIRE. The images and 3D data are transferred to the customers in real-time over the 4G/5G network, allowing them to discover any critical errors and take immediate action.
Using electric UAVs is emission-free and causes much less disturbance to people and wildlife compared to helicopters, which are traditionally used in power grid inspections. In addition to this, STELLAIRE collects data using intelligent, gimbal-controlled sensors, so that only the requested number of pictures, and pictures that show the correct angles of poles, are delivered to the customer. This ensures that they only receive the data they need, allowing them to maximise efficiency. STELLAIRE delivers the complete value-chain from data collection through the use of UAVs, data processing through QA inspections of imagery including the use of AI, and data visualization through a simple, easy-to-use inspection platform.
