Abstract

The disclosure describes a system for monitoring and mitigating damage to electrical utility structures and the surrounding environment. In some embodiments, the system includes fire boxes, arc sensors, angle switches, and disconnect switches configured to generate alert signals when a hazard is detected. In some embodiments, the system includes cameras configured to detect a hazard such as a fire or moving object. In some embodiments, the system includes light transmitters and light receivers positioned at a predetermined location away from power lines to detect objects that interrupt a line of site. In some embodiments, the system can electrically isolate a power line before a detected hazard impacts a power line.
