A 3 – Ø, 4-wire, symmetrical supply with a phase sequence of abc
supplies an unbalanced, Y- connected load of the following
impedances:
Za = 21.4 ∟ 54.3° Ω
Zb = 19.7 ∟ -41.6° Ω
Zc =20.9 ∟ 37.8° Ω
An analysis of currents flowing in the direction of the load in
line c shows that the positive and negative phase sequence currents
are 24.6 ∟-42° A and 21.9 ∟ 102° A. The current flowing in the
neutral towards the star point of the supply is 44.8 ∟36° A
