Vibration-insensitive fiber-optic current sensor

Optics Letters, 1993
The measurement of the electric current with an optical fiber sensor can be made insensitive to external vibrations that act on the leading fiber by using a circuit involving a mirrored Faraday rotator and a highly twisted low-birefringence fiber. A description of the optical configuration as well as our first experimental results are presented.

Harmonic analysis of current waveforms using optical current sensor

IEEE Transactions on Instrumentation and Measurement, 2002
This paper reports on the research and development of an optical current sensor for harmonic analysis within the electricity supply network. The device has a measurement capability, limited by the sampling frequency of the analog-to-digital converter, to around 20 kHz. We report on experimental verification of these measurements up to the 60th harmonic

Research on the magneto-optic current sensor for high-current pulses

Review of Scientific Instruments, 2008
A new magneto-optic current sensor with a dual-orthogonal configuration is proposed and demonstrated, which can resolve the problem which value of high-current pulses is ambiguous from the Faraday rotation in the conventional magneto-optic current sensor.
