Abstract
An electronic current transducer for high voltage transmission lines including a fast analog data channel for providing effective relaying information which is stablized by a slow, highly accurate, channel which is insensitive to changes in gain. In addition for dc transmission lines where polarity may reverse, offsetting or biasing allows for bipolar measurement.
