Accurate optical fiber current transducer for high-voltage direct current (HVDC) transmission

Abstract 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 °C to 70 °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.

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
