I am working on a project named automatic power factor controller. I need phase difference between the applied AC mains input signal of 230Volts, 50Hz. Can anyone help me, how to practically determine the phase difference b/w Voltage & current of the input signal????

Thanks in advance

 

voltage and current are delivered inphase, unless you share your circuit with another that has high reactive loads.

 

Do you have a way to monitor voltage and current?
