Networked electronic energy meters with power quality analysis

Aside from the obvious advantages (insensitivity to ageing, manufacturability, reliability and digital/field calibration) of electronic energy meters over their electromechanical counterparts, networked electronic energy meters will revolutionise future power systems in terms of better integration, planning, control, maintenance and billing. At the time of publication, standards for electronic energy metering are evolving; the authors have therefore discussed various additional desired functions of electronic energy meters in the emerging power scenario. The addition of these features (not yet completely specified by international standards bodies) is feasible without significantly increasing meter/deployment cost. In addition, meters that conform to the P.1451.2 standard may be inter-networked through the World Wide Web, thereby opening a new vista in power system distributed monitoring, automation and control.
