ANALOG DEVICES AN-641 handbook
The document details a reference design for a Class 1 meter intended for use in Wye-connected 3-phase, 4-wire distribution systems. It meets IEC 61036 and Indian Standards IS 13779-99 accuracy requirements, achieving less than 0.1% error over a 500:1 current dynamic range for balanced loads.
The design utilizes the ADE7752 single-chip solution which includes analog-to-digital converters and digital signal processing. Key features include differential output drivers for electromechanical counters, high-frequency pulse outputs for calibration, and logic outputs to indicate negative active power or miswiring.
