This module shows the active energy error, reactive energy error, RMS voltage error, and RMS current error results that were obtained with the TIDA-010037 CT-based reference design. This is the second of two modules for the “Calibration and metrology accuracy results” 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 TIDA-010037 reference design (2)
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.
In this section, a summary of the entire “How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs” training
