Corona Discharge Detection in Power Lines
Invisible forces often tell the earliest stories of electrical failure. In high-voltage systems, a faint violet glow or soft hiss may seem harmless, but it signals corona discharge, an electrical phenomenon caused by ionized air surrounding charged conductors. Left unchecked, these early warnings can escalate into costly disruptions.
Detecting the Unseen with Solar Blind UV Technology
Traditional inspection methods struggle in daylight, but Solar Blind UV (SUV) detection changes the game. Operating in the 240–280 nm spectrum, SUV systems filter out sunlight interference, making it possible to pinpoint UVc emissions from corona activity with unmatched precision.
Smart, flexible, and safe SUV cameras combine an image intensifier tube tuned to the SUV band with a CMOS sensor, delivering high sensitivity and versatile operation. Whether used from a safe distance on the ground or integrated into drones and helicopters for aerial inspection, they empower engineers to detect faults early, before hotspots or flashovers occur.
Recommended solutions: iNocturn SUV and i2Nocturn SUV series from Photonis are designed to make invisible risks visible, ensuring reliability and safety in power systems.
