Application of Infra-Red Thermography to the Study of Temperature Distribution on Energized Polluted Insulators

Temperature distribution on the surface of an energized polluted insulator has been measured using infra-red hermo thermovision techniques. Temporal variation of temperature has also been determined. Tests were carried out on a conventional ional cap and pin insulator unit. Results show that the maximum temperature of the energized insulator could be as high as 100°C at the regions around the pin.
