Case1:
If I have three single phase connections with each having its own single phase energy meters And I connect 1kw load on each of these phase continuosly 24/7 for a month.
Case2:
Now next month instead of three single phase connections I opt for a single three phase connection with a 3 phase energy meter and I connect the same single phase loads (1kw) on each of the 3 phases 24/7 for a month.
At the end of the month will by electricity bill in Case 2
be lower than that of Case 1
and why?
P.S. This is not a homework question, I'm trying to understand 3 phase power vs 1 phase power.
Edit:
So single phase loads don't seem to have an advantage in a 3 phase power supply system.
Now how about a single phase 2kW motor running 24/7 on a single phase supply for a month and then the next month i use a 2kw 3phase motor and run it 24/7 on a three phase supply. In this case surely the 3phase system will have an advantage of lower consumption (lower electricity bill). Isn't it?
