Three-Phase E-meter

This design, featuring the MSP430F471xx microcontroller, implements a highly-integrated single-chip electricity metering (e-metering) solution. Hardware and software designs are provided to enable calculation of various parameters for three phase energy measurement such as RMS current & voltage, active & reactive power, power factor and frequency.

  • Low-power three-phase e-metering implementation
  • Calculate parameters such as RMS current & voltage, active and reactive power and energies, power factor & frequency.
  • Based on the highly-integrated MSP430F471xx family of metering-focused MCU SoCs
  • Segmented LCD is also implemented in this design.
  • Complete hardware & software are provided, including a PC-side GUI.
