Question
GIVEN:
Three-phase System Data:
30 Source
Zine
30 Load
Source: Ean = 12020° v; Epn = 1204 – 120° v; Een = 1202120° v (grounded neutral)
Zan = Zpn = Zen = 0.1 + j1.5 N
Line Impedance:
Zine a = Ztine b = Zine c = 1 + j2 N;
Load Impedance:
Zab = 40 + j30 N; Zbc = 40 – j30 N; Zca = 50 + j0 N
Types of Faults to be Considered, assuming worst case scenario (Z, = 0):
SLGF (line a grounded), LLF (lines a & b connected), 1LO (line a open)
FIND:
please answer in 4 decimal places
Under Unbalanced Condition With Faults:
a. Load Line Currents (Ia, Ib,lc);
b. Load Line Voltages (Vab, Vbc, Vca);
