ABSTRACT:
A system for determining the sag of an overhead power transmission line to prevent flashover to adjacent objects on earth. Power line tension is measured as well as ambient temperature at two different times. From these measurements the Ruling Span of a power line can be calculated from which a determination can be made of the maximum safe current to avoid unsafe line sag.
