Answer Posted / naresh
transformer generally consistsof primary star connected &
secondary delta connected.star connection consists of 3
phase & 1 neutral wire ,so that each phase voltage is equal
to1.732 times the line voltage.similarly on secondary side
more current is required to drive the load ,it is provided
by delta connection,phase current =1.732 times line
current.for this reason transformer is connected so.

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.
