摘要：
Accurate optical fiber current transducer based on the Faraday magneto-optical effect is described for high voltage direct current (HVDC) transmission. The transducer may be used to measure DC and high-order harmonic currents in a +/- 800 kV DC transmission field. The performance characteristics of sensitivity, non-linearity, temperature stability, and harmonic accuracy of the prototype were investigated. The results show that the scale factor error in the -40 degrees C to 70 degrees C range is below +/- 0.2%. The presented optical fiber current transducer has potential applications for HVDC detection fields, such as for a polarity bus and a converter valve bridge arm.
