FLAG unfurls-modern metering and the IEC/FLAG protocol

Electricity metering is not what it was. In the past few years, advances in technology have brought dramatic changes; the traditional electromechanical meters, and associated time switches, are being replaced by microprocessor-based meters, with a variety of sensors, used to measure directly or indirectly the amount of energy consumed. These new types of meter are very versatile, supporting such facilities as multirate registers, rate switching and recording maximum demand. Here, the author describes how the IEC/FLAG communications protocol meets the needs of meter programming and automatic data collection.<
