3 phase current and voltage measument

Hi I would like to build 3 phase current and voltage measuring microcontroller based project what is the efficient way to do that
I allso seen current transformer can you please tell how much efficent it is
Best adc ic which can use for this project

Re: 3 phase current and voltage measument

I would think about using a three phase energy meter IC, e.g. from Analog Devices. It has current sensor interfaces and built-in RMS measurement circuit, also power and energy calculation.

Can you please suggest a good one
How to measure voltage
I need this build for smart mobile motor stater

Re: 3 phase current and voltage measument

Hi,

IC manufacturers and distributors have interactive selection guides to find a "good one" for your application.
You don't give any specifications, so we can't know what is a "good one" for you. So it's best to choose it on your own.

Every IC has a datasheet with application information and curcuit examples. There you will see how voltage measurement is made and what current measurement options you have.
