Low-Cost Three-Phase Electricity Meter Reference Design

TIDM-THREEPHASEMETER-F449: The design implements a basic three-phase electric meter system using the MSP430F449 smart meter SoC, the LMV324 precision op amps, and TPS76333 LDO regulator . It meets all of the requirements for ANSI C12.20 and IEC-62053 Class 0.5 meters.The MSP430F449 SoC is a low-cost option for engineers developing polyphase energy measurement systems for utility meters and industrial applications. . The LMV324 op amps are used for conditioning the voltage and current signals coming from the current transformers. The design uses a capacitive-drop power supply based on the TPS76333 to provide a low-cost power supply solution. Hardware and software design files are provided to enable calculation of various parameters for three-phase energy measurement, such as RMS current & voltage, active and reactive power and energies, power factor and frequency. With this design developers can quickly determine that the MSP430F449 e-meter SoC meets the requirements for their low-cost smart e-meter.
