Paper Abstract

Thermographic measurements have been made from the air on a small electrical power distribution station situated in the country, near a village. The objective was to study the conditions of detection of possible failures in the electric elements of the station. For this purpose, thermal images were obtained with an infrared scanner in the 8 - 14 micrometer spectral regions from heights ranging between 300 and 1000 feet. The scanner was mounted in a Porter Pilatus aircraft. Thermographic images were obtained in gray tones or false colors. The apparent radiation contrast was evaluated at different hours in spring, summer and winter. Emitted and reflected radiation was considered under various atmospheric conditions. The emissivity coefficients of the electrical elements of the station and of the background were evaluated. Images selected are presented with results and conclusions.
