71M6513 Neutral Current Measurement

Abstract

Measuring neutral currents enhances tamper-detection techniques. To measure neutral currents, a fourth current input channel is used, along with the existing three voltage and three current inputs. This application note discusses how the Teridian 71M6513, a device for 3-phase electronic power-metering applications, can implement the neutral-current measurement, with only minor hardware and firmware modifications.
