Today, in this article, you will learn how to make Three Phase AC Voltage Measurements using Arduino. At first, we will show you how to measure single-phase AC voltage and then measure three-phase AC voltage. Features of Three Phase AC Voltage Measurement using Arduino: Can measure AC voltage of any amplitude. Show individual phase voltage. LED indication for individual phase voltage. For the protection of the control board (Arduino Board), a variable resistor is used i.e. output voltage must not be more than 4.5V even when Zener diode burnout. Working…
