Optical Fibre Control-Measurement Systems Of Compound HV/HP Electrical Equipment

subject

description

Responsible electrical equipment should be controlled during the work in care of their high reliability. Traditional control measurement systems cannot fulfil the task because of the hard conditions in which the equipment may operate (various electrical potentials, electromagnetic interferences, changes of temperature, etc.). The development of fibre optic transmission media and fibre optic sensors allows the construction of new control measurement systems for cooperation with such electrical equipment as: converters, generators, treLnsforniens, switch bays, busbards, etc. Those optical fibre structures, composed of bu-ses and sensors are subject of this paper. The main attention is paid to the structure of the systems including couplers and area extention of the networks depending on the functions in the electric systems. The authors present the first stage of laboratory and field tests for optical fibre sys-tems in control-measurement networks for HV/HP substations, power everhead lines, electrical equip-ment etc.
