ComEd uses remote monitoring to explain mysterious 34-kV line momentary interruptions. FOR ALMOST A YEAR, COMMONWEALTH EDISON ENGINEERS USED TRADITIONAL TECHNIQUES to attempt to identify the cause of momentary interruptions on a 34-kV line. The techniques involved coupling relay distance-to-fault information with post-interruption aerial facility patrols to identify potential phase-to-phase or phase-to-ground contacts. Although Commonwealth Edison (ComEd; Chicago, Illinois, U.S.) exhausted all the traditional methods, the methods consistently proved to be ineffective at isolating the cause of the repeat disturbances on the line.
