Worker Safety Using Infrared

Infrared safety: using thermal technologies to protect workers

BY DOUG BARRY, FLIR Systems

Disconnect switches, elbow connectors, cutouts, lightning arrestors, oil-filled circuit breakers, and other electrical components tend to heat up before they fail. The ability to detect overheating on such equipment long before it becomes critical is essential for preventing costly unplanned outages and for protecting workers from exposure to potential arc flashes and faults. The experienced and well-trained know it’s crucial to heed industry standards about maintaining a safe working distance. That’s why more electricians and utility companies are turning to thermal imaging as a practical and more effective way to inspect energized equipment from outside the danger zone.
