Abstract

Methods and devices for aligning an optical current transducer are provided. The aligning includes, using a novel fixture having a predetermined grooved pattern therein, mounting, in a first groove of the pattern, a first portion of a cable of the optical current transducer and a polarizer unit of the optical current transducer. Further, the aligning can include mounting, in a second groove of the pattern, a second portion of the cable and a mirror unit of the optical current transducer.

Description

technical field [0001] The present disclosure generally relates to optical current transducers. More specifically, the present disclosure relates to optical current transducer alignment. Background technique [0002] Fiber optic current transducers (FOCTs) can be used to detect AC currents in transmission lines. FOCT operates on the principle of Faraday rotation as a magneto-optic effect whereby rotation of the plane of polarization of a light beam defined in a fiber optic waveguide placed near a transmission line occurs in response to a magnetic field induced by a current in the transmission line. The angle of rotation is linearly proportional to the magnetic field component of the direction on light propagation in the waveguide. Thus, the change in angle can be correlated to the magnetic field strength, which in turn can be used to calculate the current in the transmission line. [0003] FOCTs can be used to sense alternating currents using a differential current measur...
