Introduction

This section covers what is meter tampering, why is this a problem for utility providers, and some common ways a meter is tampered.

HSR and PRP Redundancy on RT Linux Training Series

This training series looks at High Availability Seamless Redundancy (HSR) and Parallel Redundancy Protocol (PRP), which are fundamental to many of the tightly-synchronized, high-reliability systems being built today. HSR and PRP work together or separate to keep systems working even when things break so that power stays on and things keep getting built. Both of them work in the low levels of the Ethernet stack to provide the applications that they serve these fundamental capabilities.

How to use the Fusion Digital Power Designer with UCD90x Sequencers

The Fusion Digital Power Designer is a PMBus based guided user interface (GUI) that allows users to configure TI’s family of UCD90X digital sequencers. This training series walks designers through how to work with the GUI to configure their UCD90X devices, and then manage and monitor their system accordingly.

How to Improve Battery Efficiency and Audio Quality with TAS5825M Audio Amplifier

As the entrance of search engine, the explosive growth in wireless speaker or AI speaker is driving the new requirements of audio amplifier - higher efficiency and better audio quality.

Facing these new challenges, TAS5825M (closed loop classD with 38W stereo output) develops a lot of advanced features compared with traditional audio amplifier, which includes:

How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs

As processing requirements for electricity meters gradually increase, it becomes increasingly difficult to find one device that meets both the processing requirements for adding advanced metrology features to smart meters while also accurately sensing metrology parameters, such as RMS voltage, RMS current, and active power.  To deal with this design challenge, one option is to use a separate metrology microcontroller and a standalone ADC.

How to design 1-phase shunt electricity meters using standalone metrology ADCs

As processing requirements for electricity meters gradually increase, it becomes increasingly difficult to find one device that meets both the processing requirements for adding advanced metrology features to smart meters while also accurately sensing metrology parameters, such as RMS voltage, RMS current and active power.  To deal with this design challenge, one option is to use a separate metrology microcontroller and a standalone ADC.

Hardening a meter against magnetic tamper attacks

In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.

Detecting magnetic tampering using hall-effect sensors

For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions.  Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.  

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.
