Abstract
A system for obtaining an accurate, real-time determination of the characteristic impedance of a length of a power line that measures the operating conditions (e.g., voltage and current) for at least two locations on the power line. These measurements are synchronized so that they represent the same instant of time. The data obtained from the synchronized measurements are fitted to a circuit model of the power line to obtain a characteristic impedance for the power line, which can be used to increase the efficiency of the use of the power line and to perform real-time assessment of the power line.
