#122780 - use a ready made one
Responding to: ???'s previous message
If you are a student and a beginer, and you are in india :( It will be very difficult to get a current transformers and other devices to measure power in smaller quantities( less that MOQ)

I would suggest buying a digital energy meter from the market ( the one that has a blinking LED) and use this led to sense the power consumption. You can use a simple photodiode to sense the led or connect a opto coupler to the led terminals ( if you open the case and make the connections.

this will solve a lot of safety problems. the energy meters that are available in the market today have all the safety features needed in such a device, it is just that they dont have a data acquisition system ( except for the rotary dials showing the power consumption)

This way it would be easier and safer to implement what you want. you use the ready made energy meter just as a power measuring device.
