Sai Prasad we can do that by simply measuring voltage and current of device and will get a VA reading by multiplying by them. But this will be only a estimate unless we get the power factor as well.

Yes @Abhi Verma voltage and current are mesurable and I’ve got the readings from the sensors and main problem is with power factor. I’ve tried it by using zero crossing detection technique using opamp but it’s totally unreliable gives out random readings…

theoretically your concept is right Sai Prasad . show me your ckt you are using to measure the power factor. may be there is an issue.
