Abstract :
The development of a current-comparator-based high-voltage reference inductor at the National Research Council of Canada (NRC) for calibrating loss measurement systems of large high voltage shunt reactors is presented. The high voltage reference inductor features an adjustable loss angle equivalent to a power factor from zero to 0.01. It has an uncertainty of less than 10×10-6 in both magnitude and phase.
