Abstract
An overhead power line insulator comprises a dielectric element () having an outside surface forming a skirt () with a head extended by a metal attachment fitting () for attaching the insulator, and a device for detecting surface leakage current flowing on the dielectric (), the device comprising a conductive ring () that surrounds the fitting () and that is in contact with the outside surface of the dielectric (). An electrically insulating protective element () is provided in the form of a collared bushing that surrounds the fitting (), being interposed between the ring () and the fitting () and extending radially so as to overlie the ring () in order to protect it from environmental pollution.
