Answer / engr.abdurrahim

As your Question, I think in your transformer is having
interturn fault or single phasing or may be LG
fault.Without load if any fuse blown means connected things
(Transformer)itself having problem.

Solution:
Do the Meggaring and check insulation between, phases at HV

Check insulation between phase to neutral, Phase to earth.
Check Earth resistance also.
