Answer Posted / atul sharma
as we know that it works on electro magnetic induction. when we applied d.c voltage across the primary winding a flux of constant magnitude will be set up in the core. hence there will be not be any self induced e.m.f in the primary winding to oppose the applied voltage.so it will draw more current as compare 2 a.c as a result it will burn the primary winding and damage the transformer this is bec d.c flow in a straight line so their is no rate of change of flux linkages as in a.c

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.
