Abstract
A method for modeling of an overhead electrical conductor, includes: collecting 3-dimensional location data of the conductor; substantially simultaneous with said collecting, acquiring a thermal measurement of the conductor with a local thermal sensor; and generating a CAD model of the conductor using the collected 3-dimensional location data of the conductor and the thermal measurement of the conductor. The CAD model facilitates thermal line analysis of the conductor, thermal rating of a power line that includes the conductor, clearance analysis relative to the conductor, and vegetation management relative to the conductor. Apparatus for determining temperature of the overhead electrical conductor, includes: a local thermal sensor that acquires thermal measurements of the conductor; and a data processor that extracts thermal readings from the thermal measurement, and processes the thermal readings and remotely collected 3-dimensional location data of the conductor to determine the temperature of the conductor.
