The power factor at which transformer operates
is unity
is 0.8 lag
is 0.8 lead
Depends upon the power factor of the load
Depends upon the power factor of the load
The
power factor of a transformer depends on the power factor of load.
●If
the transformer is supplying high loads in industries, where heavy machines
(i.e., heavy induction motors) operate with lagging power, the power factor
becomes lagging.
●If
it is supplying lamp loads, the operating power factor will be unity.
Hence,
the correct option is (D).
