Answer Posted / karthik
The current flow in a multi-stranded conductor tends to flow
more on the outer surface than in the inner surface.This is
due to the reason that the flux linkages in the multi-strand
conductors cancel each other in the inner strands than on
the outer strands.Due to this the current flow varies.Also
no alternating fluxes are produced in DC current flow.So the
skin effect is not defined for it.

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.
