Three-phase shunt-based energy metrology reference design
TIDA-010244
概述
This reference design implements Class 0.2S three-phase energy measurement using an isolated high-performance, multichannel analog-to-digital converter (ADC), which samples shunt current sensors at 4kHz to measure the current and voltage of each leg of the AC mains. The reference design achieves high accuracy across a wide input current range (0.05A–100A) and supports higher sampling frequencies necessary for power quality features such as individual harmonic analysis. Faster ADC sampling rates of up to 16ksps can be supported when using a TI Arm® Cortex®-M0+ host microcontroller for calculating the metrology parameters.
特性
- Three-phase metrology for electricity meters that meets class 0.2S active energy accuracy requirements across 1000:1 input range
- Support for three-phase four-wire (3P4W) or three-phase three-wire (3P3W) systems with shunts
- Active and reactive energy and power, root mean square (RMS) current and voltage, power factor, and line-frequency calculations
- Isolated USB Type-C® with onboard XDS110 debug probe with 5kVRMS isolation, tested across 100mA to 100A input range and 100V to 270V
- Capable of detecting magnetic tampering using a linear 3D Hall-effect sensor
- Software for energy metrology with pulsed outputs to a reference test system and displaying results on a Microsoft® Windows® PC GUI
