A current measurement technique using the magneto-optic or Faraday effect has been developed, tested and demonstrated. The device developed is a magneto-optic current Transducer (MOCT). It uses the rotation of the plane of polarization by a magnetic field exhibited in certain glasses (Faraday effect). This paper deals with the comparison of test data obtained in an extensive field evaluation of the MOCT with the design qualification data gathered during the development phase of this project. The analysis indicates that operation of the MOCT based metering system under field conditions compares favorably with performance predicted during design qualification.
