Abstract
All fibre voltage sensing using helically coiled lengths of thermally poled twin-hole silica optical fibre is presented. The thermally poled optical fibre possesses a small electro-optic response and forms the basis of an intrinsic sensor for electric fields. The helical arrangement of the poled silica fibre, from the ground to the high voltage conductor, allows an approximation to a tangential line integral of the electric field i.e. the voltage, to be calculated. The interferometric interrogation system combined with the high speed digital signal processing system allowed voltage measurements at an effective sampling rate of approximately 5000 samples per second. Preliminary lab system test results are presented.
