What causes a low voltage in the transformer?

Answer:
If this refers to a wire wound transformer, as it sounds then there is likely only two possibilities : the input voltage has dropped prier to entering the primary windings or there is a short in the windings some where within.
The only other possibility I can think of is : This is a trick question and the transformer is a step down transformer.
