Title: APPROACHES FOR ANALOG FRONT END DESIGN IN ELECTRIC POWER SYSTEM PARAMETERS MEASURING
Keywords: analog front end, measuring transducer, energy metering

Abstract: The main parameters of the three-phase electric power system are voltage, current, frequency, active power, reactive power, power factor, active energy and reactive energy. The increase of the electric energy price forces design and introduction of precise measuring devices with high accuracy. As the nature of the signals is analog and the data processing in the modern measuring devices is digital, the analog front end is of great importance. The purpose of the analog front end is to conform the range of the input signals to this of the used analog-to-digital converters and to transmit
