This module discusses algorithms that can be used to calculate metrology parameters from the ADS131M04’s sensed voltage and current samples. This is the second of two modules for the “Designing software for split-phase electricity meters that use standalone ADCs” section of the “How to design 1-phase shunt 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-010036 reference design (2)
An overview of the TIDA-010036 reference design, which uses the ADS131M04 delta sigma standalone ADC for sensing the voltage and current.
3TIDA-010036 hardware design (2)
An overview of the hardware used in the TIDA-010036 design, including the circuits used to translate the Mains voltage and current.
4Designing software for 1-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 single-phase system.
5ADS131M04 current detection mode for detecting neutral removal tampering (2)
This section discusses current detection mode, which is a special low-power mode of the ADS131M04 standalone ADC.
6Calibration 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 1-phase shunt electricity meters using standalone metrology ADCs” training series.
