What is the basic difference between earthing, ground and
neutral?
Answer Posted / harish
in general earthing and neutral is done for ac currents
grounding is for dc currents
in which earthing is used to reduce the short losses like
current shock and over heating of components
where in case of neutral is a common wire or point with
zero potential used as a reference one in connections

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.
