Answer / kj

As the secondary voltage is induced by the primary current
the frequency will follow each other. Normally the
frequency of the supply is constant so the output frequency
will remain the same.

If the supply frequency changes the output frequency will
follow this change and change also.

Answer / rakesh patel

we maintain the frequency of the transformer is constant because if we change the frequency,eddy current loss and hysteresis loss are also be change with respect to frequency. and due to losses, it is directly affects the efficiency of the transformer.that is why we have to maintain the frequency constant.

Answer / naeem anwar

ok......if we change the frequency in case of
transformer,,,then material or size of transformer will be
large if we decrease the frequency.and vice verca.

Fq=No.poles*No.of turns/120

Answer / pallvi dogra

There are no moving parts in the transformer i.e. no relative motion. That's why frequency remains constant.

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
