Abstract
A system and method for measuring length of an electrical power transmission line, and for estimating the average temperature of the line over the measured length. A signal is applied to the line and reflected from a reflection point to obtain a present measure of the line's length. A modified catenary equation uses the length measurement and other variables to estimate average temperature. This temperature measurement can then be used to determine how much power the line is presently capable of safely carrying.
