I am a Brazilian control and automation engineering student and i'm looking for the best cost/benefit energy meter IC.


My thesis is about a home/corporate energy meter monitoring through a web-browser.


I want to measure the power consumption of each circuit breaker at home (for example). Here I have a circuit breaker for each ar-conditioner unit (total of 4 circuit), each room power outlet circuit (total of 8 circuits), each room illumination circuit (total of 8 circuits) and one of each mono phase hidraulic motor (total of 3 circuits).


Is it possible to measure energy using a single neutral cable or do I have to use the neutral cable of each phase?


I know I need several IC, but which one is the best option in your opinion?
