I want to measure the instantaneous value of current at peak phase voltage in a three phase system. How can i do this ?

I need a solution which can be m-file or Simulink model, either of them is appreciated.

Hello Mansi,
you could set up a phase locked loop on the voltage, and use that knowledge to sample the current at peak values. A simpler less robust solution would be to measure voltage and sample current whenever the voltage starts to decrease. This will need filter and phase shifting to work in a real system with noise.
Regards,
Joel
