摘要: In a magneto-optic method of measuring an A.C. current in conductor, the plane rotation linearly polarized light is rotated through angle Faraday element surrounding being measure strength. This divided into two signals, with polarization planes directed at right angles to each other, which are converted by opto-electro converters corresponding electrical signals. The signals used form functional value that represents temperature. used, together first signal, determine temperature-compensated signal for current.
