Description
- TIDM-THREEPHASEMETER-F449, Low-Cost Three-Phase Electricity 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
