DIAGNOSTICS OF LINE -STICK INSULATORS

Abstract

The paper describes the possibility of applying method and means of infra-red equipment for detecting the damages in line-stick insulators at the early stage of their development. There had been researched the influence of dielectric losses of porcelain on the heat processes in insulators. It had been shown that the reveal of temperature anomaly, with the increase in temperature less than by 0,2 – 0,3 °С, by infra red equipment is possible during the increase of dielectric losses 20 – 30 times in comparison with the standard.
