Abstract
Losses of low-loss inductive components like power transformers and reactors are difficult to measure accurately because of the very low power factor. Low power factor means that accuracy of the measurement of the phase angle is a crucial factor in the measurement uncertainty. In this paper we introduce an advanced loss measurement system for measuring the losses of an air-core reactor under high voltage. The system consists of a capacitive voltage divider, a current sensor and two sampling multimeters. The high-voltage arm of the used capacitive divider is a gas-compressed reference capacitor. The low-voltage arm consists of ceramic capacitors on the feedback l...
