System Overview

As the energy and metering industry converts from electromechanical meters to Smart Grid; power-system designers have a chance to incorporate new features that were not previously possible. Today’s electricity utilities are demanding more information from meters in the residential sector, where metering has typically been limited to kilowatt hours. New features such as time-of-use tariff, loading curves, power quality monitoring, connection to home display, are desirable to improve generation, distribution, network management, customer service, and billing. ST provides the widest metering product range addressing all aspects of electricity metering applications, helping you reach your goals of high reliability, robustness and accuracy using the leading edge technologies.
