Summary

In this section, a summary of the entire “How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs” training module would be covered.  Links will be provided for the reference designs that were discussed during this training series.

Current sensor and metrology architecture options

This section compares two types of current sensors used in electricity meters: current transformers and shunts.  In addition, it discusses three different architectures for sensing the voltage and current samples used to calculate the metrology parameters.  These architectures include a SoC-based architecture, AFE-based architecture, and ADC-based architecture.

Introduction to TIDA-010036 reference design

This section provide an overview of the TIDA-010036 reference design, which uses the ADS131M04 delta sigma standalone ADC for sensing the voltage and current necessary to calculate metrology parameters.  The TIDA-010036 design targets Class 0.5 single-phase two-wire meters with shunt current sensors and has a compact, magnetically immune cap-drop power supply to power the design from AC mains.

TIDA-010036 hardware design

This section provides an overview of the hardware used in the TIDA-010036 design, which includes the circuits used to translate the Mains voltage and current to the voltage waveform sensed by the ADS131M04.  In addition, it covers the TPS7A78-based cap-drop power supply used in this design.

Designing software for 1-phase electricity meters that use standalone ADCs

This section covers the initialization code and algorithms that can be used to calculate metrology parameters in a single-phase system using the sensed voltage and current samples.

ADS131M04 current detection mode for detecting neutral removal tampering

This section discusses current detection mode, which is a special low-power mode of the ADS131M04 standalone ADC, that can detect the presence of current when someone has tampered with a meter by removing its neutral connection.

Calibration and metrology accuracy results

This section discusses the procedure used to calibrate the TIDA-010037 design and the results obtained with this design.

Summary

In this section, a summary of the entire “How to design 1-phase shunt electricity meters using standalone metrology ADCs” training module would be covered.  Links will be provided for the reference designs that were discussed during this training series.

Getting Started with Current Sense Amplifiers - Advanced Topics

Section 3 of this training series introduces three advanced topics related to current measurement with current sense amplifiers.

Introduction

Tune in to learn more about meter tampering, why it is a problem for utility providers and some common ways a meter is tampered.

Detecting case tamper attacks using inductive switches

The first line of defense against tampering by bypassing current, reversing connections, and disconnecting leads is the meter case. Due to this, it is common for utilities to require some form of intrusion detection system to detect when someone opens a case.  In this section, we will cover how to detect someone trying to open the case of a meter.

Summary

In this section, a summary of the entire Anti-tamper Techniques to Thwart Attacks on Smart Meters training series will be covered.  This summary includes the Detecting Case Tamper Attacks Using Inductive Switches, Detecting Magnetic Tampering Using Hall-effect Sensors and Hardening a Meter Against Magnetic Tamper Attacks sections of the training series.
