Connection Of System Measuring Voltages And Currents Of High Voltage Power Line To A Microcomputer By Optical Fibre Link

The prototype of equipment for service of the measuring units of power high voltage line is presented. That system is composed of the transmitter /with A/D conversion/, optical fibre data link and receiver feeding the output into the microcomputer. The application of this equipment in the automatic protection system protecting the power network against short-circuit is described.
