Title:
ELECTRIC CURRENT DETECTOR
Document Type and Number:
Japanese Patent JP2001343401
Kind Code:
A
Abstract:
To reduce electric current detection errors associated with a temperature rise, in a current detector using a Rogowskii coil.
A load resistance value is matched and a drop in output voltage associated with an unavoidable increase in the internal resistance of a Rogowskii coil under a temperature rise is offset by an increase in the Rogowskii coil electromotive voltage resulting from the temperature rise, thereby reducing the errors in current detection.
