Class 0.5 Three-Phase Smart Meter Reference Design

This design implements a complete smart meter design using the MSP430F67641 polyphase metering System on Chip. The design meets all requirements for ANSI/IEC Class 0.5 accuracy and the firmware provided calculates all energy measurement parameters. The F67641 SoC features 128KB of on-chip flash plus a 320-segment LCD controller for a single-chip solution to low-cost polyphase meter design challenges.

Low-cost three-phase electricity meter for Class 0.5 accuracy TI Energy Library firmware calculates all energy measurement parameters including active and reactive power and energy: RMS current and voltage: power factor: line frequency: fundamental and THD readings Add-on communications modules for wireless communications standards such as ZigBee®: Wi-Fi®: Wireless M-Bus: and IEEE-802.15.4g. Both 2.4 GHz and Sub-1 GHz. Built-in 160-segment display Powered from three-phase line voltage
