Title: Power transmission line monitoring system

A method for monitoring the sag of an overhead power transmission line comprising the steps of: measuring the tension of the power line; producing an electrical signal representative of the tension measurement; processing said electrical signal in accordance with a predetermined tension-sag relationship to produce a second signal which is a function of sag of the power line; transmitting said second electrical signal to a distant location in a predetermined transmission mode; receiving the second signal at the distant location whereby current in the power line is adjusted in accordance with the received second signal.
