Measurement of Electrical Discharge Parameters Using Optical Fibres

Abstract

A consequence of the development of optical fibre technology for communications has been the application of optical fibres to the sensing of a wide range of physical and chemical parameters. Many of the properties of fibres that are important for communications' are significant for sensing: these include their insulating nature, their small dimensions, and their immunity to high voltage and electromagnetic radiation. These attributes are particularly significant for sensing electrical discharges, and this review presents a discussion of the potential of optical fibre sensing for discharge parameters, the results of some recent optical fibre measurements made on corona and glow discharges, and suggestions for other discharge. probing approaches using optical fibres.

Testing RFoF link for transmitting HF-OTHR signal between transmitter and receiver shelters

“…This would galvanically isolate equipment shelters and critical components within: Frequency Control Rack (FCR) for radar signal generation and digital processing of received signals on Rx side and Power Amplifier (PA) on Tx side. As optical fibers are extremely resistant to electromagnetic interference (EMI) this would also solve the problem of external discharges damaging HF-OTHR equipment [6].…”
