Infrared Inspection of Electric Utility Equipment

AbstractIntroductionPower GenerationSubstationsTransmission and DistributionConclusionsUnexpected failures in a utility provider’s electrical equipment can result in lost customer minutes and damage to valuable equipment. They can also undermine consumer confidence in their power provider. Routine infrared inspections coupled with effective repairs can pay huge dividends for electrical utilities by helping to reduce unscheduled downtime. Drawing upon a database compiled from over seven years of infrared inspections of electric utility equipment, this paper will discuss common problems such as connections and lightning arrestors as well as some not so common problems associated with oil filled equipment and insulators.Get price
