SBAS949A February 2020 – February 2021 ADS131M06
Each channel of the ADS131M06 is identical, giving designers the flexibility to sense voltage or current with any channel. Simultaneous sampling allows the application to calculate instantaneous power for any simultaneous voltage and current measurement. This section provides a diagram depicting the common energy metrology configuration that can be used with the ADS131M06. A Rogowski coil can alternatively be used to sense current in the following example wherever a CT is used. The integration to determine the current flowing through the Rogowski coil is done digitally if that modification is made. RC antialiasing filters are not shown in the following diagrams for simplicity, but are recommended for all channels.
Figure 9-3 shows a three-phase configuration where live currents are monitored using CTs and the phase voltages are measured using a voltage divider.
