Optical Fibre Control-Measurement Systems Of Compound HV/HP Electrical Equipment
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…
Multiservice Optical Fibre Local Area Networks For Data Transmission And Telemetry In The Electric Power Industry
The paper contains a review of a few of experimental optical fibre multiservice and multibranch local area networks /LANs/. Systems accomplish transmission, distribution and processing of analog or digital signals from numerous sources or measurement terminals. The authors put stress also on the possibility of combining transmission properties of fiber optic networks with fibre optic sensors. Several construction problems and chosen properties of multiport /multiterminal/ optical buses /networks/ have been considered. All examination systems of optical fibre LANs are discussed in respect of application them as telemetric, transmission, telesignaling and telecontrol systems for the power ele…
Research Toward The Optical Equipment For An Autonomous Robot For TviV Environment
The paper consists of three major parts: basic technical problems in very high power/megavolt environment, signal processing and mechanical equipment for this environment, construction of a sensor equipped robot for this environment. The first part contains mainly metrological confinements and reliability considerations for the optical, optoelectronic and electronic part of a system. The second part contains mechanics and robotics problems. The result of these two parts is a choice of a system to be realized.
Optical Fibre, Local Measurement Systems For Ships
Modern ships are more and more fully equipped with auxilliary control and supervising sys-tems. These systems, in turn, are more and more frequently built with the aid of fibre optics. Fibre optics ensures proper reliability of such a system in a harsh marine environment. This environment includes: marine climate containing salt spray, mechanical vibrations and shocks, electromagnetic and magnetic interferences, changing temperatures etc. All of these harmful reactions may influence the system /worst case marine environment/ during a single sailing cruise. We will consider here the worst case environment for a marine-grade fibre optic system.
Lightguide Technology For Adverse Industrial Environments
The lightguide technology has several unique fetures that open up new possibilities of its applications in alverse environments. These factors make this technology attractive in comparizon with classical metal cable based and radio technologies. In the paper we will review relevant works carried out in this country, namely: techno-logical specialization processess for industrial application oriented optical fibres and cables, classification of adverse environments and design rules for cables and optoelectronics, description of our technological facility, fiber optic health protection systems in adverse environments, example of real life applications of ruggedized fibre optic systems in HV/H…
