ABSTRACT:
A system for determining the sag of an overhead power transmission line to prevent flashover to adjacent objects on earth. A tension measuring device is provided to produce a sign as a function of powerline tension. The signal is processed and transmitted to a distant location by cellular communication to a distant central monitoring station. Knowing the sag-tension relationship of the monitored line the sag is determined. Thus action may be taken if the powerline sag becomes excessive.
