Abstract
PURPOSE:To prevent the fluctuation of an optical axis due to a rise in temp., by providing the light incident and emitting points to the Faraday effect material of an optical current transformer below the horizontal plane passing the uppermost part of the conductor inserted in the central part of the Faraday effect material. CONSTITUTION:A conductive to be measured is inserted in the central part of a Faraday effect material 1c and an optical head 5c wherein optical fiber end surface parts 16, 17, a polarizer, an analyzer 13 and lenses 14, 15 are received in a head case is arranged to earth potential. The light from the optical head is incident to the Faraday effect material 1c from the incident point 8c thereof to travel round the Faraday effect material and reflected by a reflecting mirror 7c to be guided to the optical head 5c through the same route. The incident point 8c of light is positioned below the horizontal plane 11c passing the uppermost part of the conductor to be measured to prevent the effect of the disturbance of an optical axis due to the shimmer phenomenon of high temp. gas generated by a rise in temp.
