Three-phase PCB Rogowski coil-based electricity meter reference design

TIDA-011013

Design files

Overview

This reference design aims to allow users to use different types and sizes of Rogowski coils in an electricity metering environment. The design supports a wide current range (0.25A to 115A) and 0.2% accuracy according to IEC and ANSI standards with software and hardware integration methods. This design offers a high level of flexibility and customization using a standalone analog-to-digital converter (ADC) and programmable microcontroller.

Features
  • Single-chip amplifier-integrator conditioning circuit for 3-phase electricity meter
  • Hardware and software integration methods
  • Wide current range made for multiple metering applications
    • Residential, commercial, and industrial
