Unbalanced load on 3 Phase distribution grid without neutral.

Hey,

I have a question. When you connect a resistive load in star to the power grid but you don't connect the neutral wire and the load is unbalanced (R1 >> R2 & R3) then there will be a potential difference between N0 & N (see picture). I know how you can calculate this theoretically but i want to measure this. Can i just put a multimeter between N0 & N like on the picture or is there a better/safer/more accurate way?

Thanks!

Yes, you can measure this with a multi meter but be aware of the phase shift.

One much better way: Let your mate do it for you.

Anyway be careful.
