Dynamic line rating system with real-time tracking of conductor creep to establish the maximum allowable conductor loading as limited by clearance

摘要

Maximum transmission line or conductor loading of an overhead transmission line or conductor spanning two transmission line towers is determined by using a sensing device clamped to the overhead transmission line. The sensing device acquires real-time information that is used in an iterative process to determine sag, limiting temperature, maximum current load and minimum clearance of the transmission line or conductor.
