How to design high-accuracy CT-based split-phase electricity meters using standalone metrology ADCs
Resources
In this section, we'll provide a summary of this training and provide you links you can follow for more information on this reference design. To wrap things up as a review, one advantage of this design is that it allows you to increase the sample rate without compromising on accuracy. The higher sample rate enables capturing higher harmonics.
This information can be used by the utility to see which customers' nodes are causing bad power quality. In addition, one advantage of this design is that it has a high accuracy across a wide dynamic range. This will help ensure the most accurate calculation of metrology parameters, like Active Energy, which in turn would ensure the most accurate billing for highest revenue utility customers.
Also, by using the ADS131M04 for sensitive voltage and current, we have flexibility in selecting the microcontroller from a wide variety of options. You can select my microcontroller based on any specific application requirements, such as requires CPU bandwidth, security features, or integrated communications stacks.
