For a fully transposed transmission line
-
- positive, negative and zero sequence impedances are equal
- positive and negative sequence impedances are equal
- zero and positive sequence impedances are equal
- negative and zero sequence impedances are equal
Correct Option: B
Where Zn → neutral impedance
ZS → Self impedance
Zm → mutual impedance
Let Z0 → zero sequence impedance
Z1 → +ve sequence impedance
Z2 → – ve sequence impedance
| Z012 = |  | Z000 |  |
| 0Z10 | |||
| 00Z2 |
∴ Z1 = Z2 = ZS – Zm
