Answer / sayanta ganguly

Out of all machines Power Transformer have highest
efficiency. Power Transformer is a Static Machine and its
efficiency is nearly 100% that means full efficiency. power
transformer generally operated at full load. Hence,
it is designed such that copper losses are minimal and
efficiency at maximum.

Answer / vimal baldaniya

ofcourse transformer but dry type transformer because it
has less losses compared to other type transformer.
