How IoT Sensors Are Detecting Underground Cable Faults
In this episode, Lucas and Luna explore how IoT sensors are catching underground power cable faults before they escalate into blackouts. They dive into the physics of partial discharge — the tiny electrical sparks that signal insulation breakdown — and how distributed acoustic sensing, or DAS, turns fiber-optic cables into thousands of vibration detectors. The conversation centers on a 2025 pilot by a European utility that used DAS to locate a fault within 15 meters along a 40-kilometer cable, preventing a potential substation failure. They also discuss the cost shift from manual cable…
