Short Circuit Calculations

Hello friends..

I have a relatively simple 2 bus system here and I think i know how to find the short circuit fault currents but the problem is my current lecturer uses a different method from the one I have been taught in the past and we do not get same answer.

Ok so please tell me what your answer will be for the following circuit if a three phase fault occurs at bus 2. Basically find me the 3phase short circuit current at bus 2.

[Generator]|bus 1 (11kv)-----}{transformer----|bus2(132 kv)

Generator ratings are

X=26%, 66.6MVA, 11KV

Transformer

X=12.5%, 75MVA, 11/145KV

Sbase=100MVA Vbase=132KV

i hope this diagram makes sense

No tx lines involved here.

THANKS IN ADVANCE GUYS!! i have spent lot of time breaking my head over this but no luck..i hope you will get same answer as me :D
