How to measure power consumed by mains device
I have the following question:
In my home I have certain devices such as my fridge etc. of which I would like to measure their powerusage. For practical reasons I would like to use current convertors (CT's) to do the measuring for me. At the moment I have some current convertors with a rated secondary output of 1A. Yet I do not seem to find a device that allows me to accomodate this output and convert it to kwh. As a plus I would like that the measuring devices has a pulse output for usage in an other project I am working on.
Can anyone give me advices on this matter?
