I have a refrence single phase voltage of 220VAC.
Now there are three (3) phase supply; a phase to neutral measure average of 220vac plus or minus
At any time I need a single phase output, out of this three phase supply with the nearest voltage value to my refrence voltage of 220VAC to be choosen to operate a 12VDC relay.
Kindly help me out with basic and simple circuit to achieve my aim
THANKS.
