Application of Composite Insulators: Perceptions versus Service Experience by Igor Gutman

European TSOs and DSOs started a collaborative research project to benchmark actual service experience with composite insulators. The project included collecting service experience as well as comprehensive testing of insulators removed both from storage depots and also from service – about 9 million units in total and with average time in service of 24 years. Primary interest was placed on overhead line insulators but substation insulators were also analyzed. This presentation reviews the key findings.
