Hello readers,
I planned to give 3phase voltage to ADC of micro controller , for doing this i have done the voltage divider network and i have tapped 5v AC.Now this 5V AC is to be given to ADC of micro controller.Can i give this ac voltage directly to ADC or i should use any isolation in between.If isolation to be done then how can i do that.please help me with circuit.
