Detection of problems in high-voltage power lines is difficult with ground-based equipment because IR sensor units are subject to error caused by background thermal patterns such as clouds and tall trees. Travel is often slow due to soft sandy soil, moist areas, gullies, and creeks. Such difficulties were eliminated by the use of an airborne Probe Eye Scanner/Normal Color Video System (PESNVS) in an exploratory test. The equipment was mounted in a Piper Twin Comanche and was flown over power lines in east Florida. For ground verification, the PESNVS was mounted in a 4-wheeled vehicle and operated in field surveys under the high tension power lines where three anomalies had been detected aerially. Faulty components (operating above normal temperature) of the same high tension transmission lines were confirmed by the ground surveys.
