Main Question or Discussion Point

how much is the current in a neutral line of 3phase and 4 wire system with voltage of 0.38/0.22kV. where we have 8 loads which each load is 2 kVA. 3 loads connected to each phase of A and B and 2 loads connected to phase c.

Sounds like a homework problem. Use the template and show some attempt to solve it yourself and ask questions about whatever you are stuck on.

you will have current that neutralise any asymmetry in your load - in your case that is 1 load on A and B each. which is equal to 1 load on C if you think about vectors (absolute value).

you will have 2 (kVA) / 0,22 (kV) = cca 10 A in neutral.
