Abstract
A magneto-optical measuring transducer for measuring high-voltage currents has a measuring sensing element positioned adjacent a conductor carrying the high-voltage currents to be measured. The sensing element is designed as a pair of similar and adjacent light conducting coils. The polarization plane of linearly polarized light within the coils is rotated according to the strength of a magnetic field produced by the current in the adjacent conductor. A compensator is also provided comprising a pair of light conducting coils. The compensator is spaced from and optically connected to the measuring sensing element. A variable magnetic field is provided adjacent the compensator and the change in polarization of light waves conducted within the compensator is detected by a detector and compared to the polarization of light fed through the measuring sensing element.
