Abstract
A, fibre frequency coded optical fibre voltage sensor for alternating current mains which is characterised in that, using a single mode optical fibre, the voltage applied generates an optical signal whose amplitude is frequency modulated. The frequency modulation encodes the amplitude and waveform of the applied voltage. The system consists of a continuous wave, coherent light source which supplies an optical fibre interferometer, a sensor element in the interferometer and a high power optical/voltage transducer photodiode. The optical system is an optical fibre interferometer, but is not a conventional interferometric (or phase) sensor and does not require any drift compensation, due to the design and method of operation employed.For application in the transmission and distribution of electricity.
