Question 14 A 

Full explain this question very fast solution sent me step by step, 

 

29: if a three phase 220KV 50Km long transmission line loaded 10MVA. The
conductor used is ACSR with resistance equal to 0.0566 per Km. The active
transmission losses shall be:
1. TL 8.5 KW
2.
TL
117 W
3. TL 5.8 KW
4. None of the above.
R=0.0566 x 50=2.83 ohm
VI 10MVA 10X10^3 KVA
220 x = 10000
I=(10000/220)=45.45A
TL=1 x 1 x R= 45.45 x 45.45 x 2.83-5847.10W-5.8KW
Ans 3. TL= 5.8KW
