This module discusses three different architectures for sensing the voltage and current samples used to calculate the metrology parameters. These architectures involve using a SoC, metrology AFE, or standalone ADC. The advantages of the standalone ADC architecture compared to the other two architectures is discussed. This is the second of two modules for the “Current sensor and metrology architecture options” section of the “How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs” training series.
1Current sensor and metrology architecture options (2)
This section compares two types of current sensors used in electricity meters: current transformers and shunts.
2Introduction to the TIDA-010037 reference design (2)
This series provides an overview of the TIDA-010037 reference design which uses the ADS131M04 delta-sigma standalone ADC for sensing the voltage and current.
3TIDA-010037 hardware design (2)
This section provides an overview of the hardware used in the TIDA-010037 design.
4Designing software for split-phase electricity meters that use standalone ADCs (2)
This section covers the initialization code and algorithms that can be used to calculate metrology parameters in a split-phase system.
5Calibration and metrology accuracy results (2)
This section discusses the procedure used to calibrate the TIDA-010037 design and the results obtained with this design.
A summary of the entire “How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs” training series.
