Single line to ground fault current at the HT Panel

Dear Guys,

I have a query related to SLG fault current at HT panel. I have attached one Snap shot of SLD in which the supply is flowing through the AVR (If it is Y-Y not earthed &/ or Delta Delta), I just wants to know that would the SLG fault current be generated at EXI. 33KV OUTDOOR PANEL at the time of short circuit (earth fault) or not. Kindly help me related to this issue.
If yes, then please share the results.

Thanks,

yash arora
