Dear Friends ,
I need to measure 3 phase Vrms , Irms ,Energy(kwh) .
Please suggest me a suitable setup to measure the same using a microcontroller .:
Following are the features required:
1. Mcu should be isolated from the high voltage analog side.We can use some energy measuring ic -> isolator -> mcu .
2. I want good precision.
Also please clarify whether the energy meter ic does all the sampling and gives accumulated energy per phase .
which would be the better option : MCP3919 OR ADE7758.
