Magneto-optical high voltage current measuring transducer

摘要

A magneto-optical measuring transducer for measuring high voltage currents with a measurement sensing device which carries high voltage potential and is designed as a light conducting coil, with which linearly polarized light is rotated with respect to its polarization direction, in dependence upon the strength of a magnetic field produced by the current to be measured, the light conducting coil being in the form of elements, which lie in respective planes of curvature disposed at right angles to one another, with such elements following one another in the propagation direction of the linearly polarized light.
