Ok, iam looking for the correct procedure ,correct device which suits my application.will come back soon.thank you.

Hi friends,
does anybody know tha IC or device which is used for converting incoming 3 phase voltage and current to 0-10V range output?

for example each line voltage R,Y,B individually should gi ...

thanks for your responses guys,i was busy a little with other project,hence took a gap in this project.I will come back again with my queries after creating and testing my model.

Can i connect a potentiometer directly without ADC to 16F877a to read the values directly ? Pls reply soon. waiting for it. I want to connect the pot as Analog Input.
