Self-powered system for the detection and location of faulted insulators in overhead distribution power lines

Post insulators as the weakest component of transmission lines, are highly exposed to breakdown. Insulators breakdown leads to outage and economic loss for transmission companies. Faulted post insulator detection and location is very important to minimum duration of outage. Depending on type of post insulators types, they can be detected in case of breakdown. Silicon rubber post insulators as new generation of insulators, have better insulation characteristics compare to others. Away from all of its advantages, detection and location of broken ones are difficult for system operator due to no external damage. In this thesis design of a self-powered system to detect the broken silicon rubber post insulator has been pursued. An innovative optical effect triggered by self-powered system has been deployed to detect faulted post insulator.
