Abstract
PURPOSE: To accomplish accurate measurement of inductance for current transformers by removing residual magnetism thereof through gradual reduction of the output voltage thereof down close to zero after the selection of output voltage and frequency.
CONSTITUTION: The residual magnetism of a current transformer 3 is removed by gradually lowering the output voltage E of the current transformer down close to zero after the selection of the output voltage and the frequency. This enables highly accurate measurement of the inductance for the current transformer 3.
