Supply to one terminal of a $$\triangle$$ - Y connected three-phase core type transformer which is on no-load, fails. Assuming magnetic circuit symmetry, voltages on the secondary side will be:

When a transformers winding suffers a short-circuit, the adjoining turns of the same winding experience

Two transformers of identical voltage but of different capacities are operating in parallel. For satisfactory load sharing

Two transformers of the same type, using the same grade of iron and conductor materials, are designed to work at the same flux and current densities; but the linear dimensions of one are two times those of the other in all respects. The ratio of $$kVA$$ of the two transformers closely equals
