Abstract

Apparatus for measuring current in a conductor characterized by a magneto-optical current sensor employing the Faraday effect to measure current in a high voltage transmission line. Polarized light having a predetermined plane of polarization is directed into the sensor which plane of polarization is rotated by magnetic field lines generated by the current in the conductor. A bimetal coil rotates the sensor to achieve temperature stability of the current signal in the temperature range of -40.degree. C. to 140.degree. C.
