Abstract
An optical current transducer (OCT) with a bulk type Faraday sensor de monstrated 0.3 % class accuracy for metering. The Faraday sensor had B i12SiO20 (BSO) single crystals with right and left optical rotatory po wer to cancel out temperature dependency. A prototype 161 kV OCT insta lled in a TVA substation verified 0.3 % class performance. The OCT had the Faraday sensor, a gapped magnetic iron core, a 1.6 m optical insu lator, and an optical interface.
