We know that, in case if there is a faulty insulation,or
sc, the current is bypassed to earth through the earth wire
that has low resistance.Actually, what will happen to that
current that flows through gnd?In that case,if we come in
contact with that faulty appliance, wont that current flow
through us as we form a closed path by standing in gnd?Is
grounding a safety measure?

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.
