Abstract
An optical current transformer, which uses a Faraday cell for detecting the intensity of a magnetic flux induced in a circular iron core, has plural windings having the same number of turns provided on the core in a manner that overall width of the windings are evenly wound along the whole part of the circular iron core, and terminal of the windings having the same polarities are commonly connected by cables.
