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.

During Testing of Maintenance Free Earthing, How deep should be the Spikes of Earth Test Meter should be inserted in the soil(one spike is 15 Meter & Other spike is 30 Mtrs away from the Main Earth Electrode. Because, recently, we observed that when spike is inserted 3-4 Inch in the earth- results are better, If spike is inserted 1 feet deep than results are increasing.
