DATA ACQUISITION AND PROCESSING SYSTEM FOR SMART MEASUREMENT OF POWER IN HV GRIDS BY OPTOELECTRONIC MEANS

The present concerns related to the smart use of energy require changes in the way in which the electric energy consumption management should be performed, under the circumstances connected to the assurance of electric energy delivery continuity, reduction of polluting emissions, consumption metering and use of flexible tariffs. In this paper, an analysis of the power measuring system based on an optoelectronic system for voltage and current measurement in the high voltage networks, where the supply and data transmission to and from a high potential is exclusively achieved by fiber optic, is presented. It is shown to what extent this measuring system with information multiplexing can be achieved, also the measurement uncertainty resulted at power measurement.
