Answer Posted / amit
In balance condition neutral current is zero. Flux in all
three phases are in addative nature.
flux in R + flux in Y + flux in B = 0(zero)
but in your case it is different because of differnt
currnet in phases, which will affect and cause a unbalance
condition, will produce a flux in neutral and current
flowing through neutral. But in your case it is 25A which
is to much unbalance condition.
