Introduction

This section covers what is meter tampering, why is this 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.

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.  

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.

Summary

In this section, a summary of the entire “Anti-tamper Techniques to Thwart Attacks on Smart Meters” training module would be covered.  This summary would cover 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. Links will be provided for the reference designs and design tools that were discussed during this training series.

Overview of temperature measurement in heat meters

This section introduces the heat and cold meter training series. The series covers the basics of RTD sensors and their usage in heat and cold meters, as defined in the EN1434 set of standards.

Measuring RTD sensors with Delta-Sigma ADS1220 family

ADS1220 Delta-Sigma family uses the ratiometric approach for measuring RTD sensors with the built-in current excitation source. Offset and gain calibration are required before the resistance measurement is converted into a temperature reading by the application MCU.

Differential Temperature Measurement sub-system reference design

TIDA-01526 implements a high-precision Differential Temperature Measurement (DTM) subsystem using a 24-bit, low-power, Delta-Sigma ADC. Heat and cold meter DTM subsystems typically use two 2- or 4-wire RTDs such as PT100, PT500 or PT1000 and can achieve measurement accuracy of 20 mK over a water temperature range of 3°C to 180°C. The MSP430FR6047 application MCU converts the resistance value into a temperature reading in TIDA-01526.

Digital temperature sensor replacement of RTD sensors with TMP116

The TMP116 digital precision temperature sensor for the -55 to +125ºC range achieves higher accuracy than the Class AA PT sensor with a 1-point calibration. A small PCB including TI's TPD1E10B06 or TPD1E04U04 protection devices can be sealed into a RTD metal tube and meet the EN 61000-4-2 and -4-4 levels of ESD protection. The 64-bit internal EEPROM inside TMP116 stores user defined calibration data into the digital temperature sensor, simplifying integration with application MCUs, such as MSP430FR6047, FR6989 or CC13xx/26xx wireless MCU families.
