Question
GIVEN:
Three-phase System Data:
30 Source
Zine
30 Load
Ean = 12020° v; Epn = 1202 - 120° v; Een = 1204120° v (grounded neutral)
Zan = Zbn = Zen = 0.1 + j1.5 n
Source:
Line Impedance:
Zine a
Zline b
= Zline 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 (Zf = 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:
c. Load Power Profile (Pr, QT, ST,pfr);
d. The Fault Current (If)
