Applications of high-voltage fiber optic current sensors

Various applications of a fiber optic current sensor are explored. Flexibility and inherent beneficial features of the technology make it appropriate for many applications, including some novel protection applications. These applications include regular high-voltage AC metering and protection, accurate wide dynamic range metering, high voltage DC, high current DC, portable calibration reference, generator monitoring, generator protection, and high-current AC applications. Some novel uses of the technology, including optical summation of currents where conductors are quite large or far from one another, are also discussed.
