Mr. mohh sahid m not satisfied for ur answer to the que
weather the size of transformer increases or decreases
withchange in fr
for more detail go to the answer given by me

Answer Posted / Mayank Kumar Jaiswal

The size of a transformer, specifically its physical dimensions and kVA rating, can be affected by changes in operating frequency (fr). In general, an increase in operating frequency leads to a reduction in the physical size of the transformer due to decreased core and winding sizes. However, there are limits to this scaling, as smaller dimensions can lead to increased copper losses and reduced efficiency. It is essential to balance the requirements for size reduction with maintaining acceptable levels of efficiency and insulation clearances.

A 15 kw squirrel cage motor having a maximum efficiency of 90% on a continuous full load has temperature rise of 42 degrees celcius after 30 min and 52 degrees celcius after 1 hr under the above operation conditions. a) calculate its final steady state temperature rise on continuous load and the heating time constatnt. b) if the motor is operated on a short load for 9 min estimate its temperature rise. c) calculate the maximum overload that can be applied on a short, 9 min rating so that the temperature rise is the same as the final steady state temperature rise on continuous load.
