Sequence Impedances For Transmission Lines

Hi everybody,

 

I have some problem to get the positive and zero sequence for a 3 phase transmission line with line resistance=0.06642 ohm and line inductance=0.00022 Henry.

This transmission line is connecting a step down transformer (33/11KV, 40MVA, Z=0.075) and an R&L load.

What are the formula to get the zero and positive sequence for this transmission lines?

 

Hope there is anyone that can help me to solve this calculation since i've been working with it for the past few weeks but can't find any solution for it..TQ
