Fibre-Optic Links For A Measurement And Control System At A HV Laboratory
The paper presents a fibre-optic linking system for a measurement and control system installed at an industrial HV laboratory. The indirect voltage and current measurement system is furnished with the E0/0E transducers and FO links. The exploitation requirements on the adequate measurement accuracy and reliability have necessitated the inclusion of additional, digital PO link feedback from the computer control system. The proposed measurement system with the FO link has been installed at an HV laboratory transformer of an electric power station and successfully tested together with the overall equipment.
Fiber-Optic Insulating Link In A Telecommunication System For An Electric Power Plant
The paper presents a fiber-optic insulating link coupling electric power substation with a dispa-tching telecommunication center. The advantages of employing the FO link in the power plant telecommunication system include insulating properties, resistance to EMI and high transmission capacity. The technical and economical analyses are complemented with the example of an application of the link to the 110/15 kV station. The two-directional communication system provides transmission of voice, telemetry, telesignalization and remote control signals.
