Answer / k.prakashchandra

The above is correct.But transformers with same capacity and
voltage having % impedances in the ratio 1:2, is not
believable.The load sharing will be in 2:1 ratio if they are
connected in parallel.

Answer / aamod tripathi

This should not be done ideally (Parallel operation not
permitted) . However the load can be distributed exclusively
and independently on each transformer (Each Transformer
connected to indivisual (incomer) feeder and independent
loads(outgoing))

why we do occ & scc test in transformer ?how we can do it ?

Please help me regarding my one concern. - During earth pit testing we noticed that the Clean earth pit and dirty earth pit showing continuity (Resistance value - 5ohm) . I want to know that if both earth pit have separate location and there is not internal looping between PIT then why such continuity is showing on it . Because of this issue the field side all earthing point showing short. In PLC panel we are providing two types of earthing cable which is coming from separate earth pit (Clean and Dirty earth pit) because of earth PIT showing short our PLC is not complying spec . please help regarding this issues.
