We have a corona camera (corona is the glow round a conductor at high potential) which is mounted to our DJI Matrice drone. With this drone we are able to fly over electrical power cables and substations and the specialised camera (with dual sensors in UV and Visible) we can detect costly power leakages that can be subsequently repaired.
The camera takes video footage of the electrical elements that require inspection and reveals sources of electrical corona, acting as high sensitivity testing equipment which provides reliable and accurate information about electrical (and mechanical) faults. The camera also works in conjunction with external GPS and ambient condition information which then integrates with the footage recorded.
