Introduction

This section covers what is meter tampering and why is this a problem for utility providers.  It also covers the advantages of shunt current sensors.  In addition, it introduces the isolated modulator and isolated metrology AFE architectures for adding isolation to shunts.

High-Side power supply options for powering shunt sensing devices

For both isolated modulator and isolated metrology AFE architectures, high-side power supplies are needed for each phase.  In this section, the different high-side power supply options that are available are discussed, which include cap-drop power supplies, isolated DC/DC power supplies with external transformers, as well as isolated DC/DC power supplies with transformers integrated. 

Implementing isolated shunt sensors using metrology AFEs and external isolators

In this section, the isolated metrology AFE architecture will be discussed.   The software and hardware design considerations for this architecture will be discussed.  In addition, the TIDA-01550 isolated metrology AFE reference design will also be discussed.

Implementing isolated shunt sensors using isolated delta sigma modulators and digital filters

In this section, the isolated modulator architecture will be discussed.  The software and hardware design considerations for this architecture will be discussed.  In addition, various isolated modulator designs will also be discussed and compared.

Comparisons between isolated shunt sensing architectures

Both isolated modulator and isolated metrology AFE architectures have their advantages with respect to each other.  Depending on system requirements, one architecture may be more feasible than the other.  This section compares the two isolated shunt sensing architectures and discusses which architecture is best for different system requirements.

Summary

In this section, a summary of the entire “Polyphase Current Measurement with Isolated Shunt Sensors” training module would be covered.  Links will be provided for the reference designs that were discussed during this training series.

Universal data concentrator supports Ethernet, 6LoWPAN RF mesh and more

IPv6-based communications are becoming the standard choice in industrial markets such as smart meters and grid automation. The universal data concentrator design provides a complete IPv6-based network solution integrated with Ethernet backbone communication, 6LoWPAN mesh networking and more. The 6LoWPAN mesh networking, which adopts an identical layering architecture to the WI-SUN FAN, addresses key concerns such as standards-based interoperability, reliability, security and long-distance connectivity.

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.
