1]how the voltages and frequency are achieved on ships.
2]how does the line and phase voltages are related on ships.
Answer Posted / suseendran
1. Yes ships do have generators. Using AVR's and controlling
prime movers speed, voltage and frequency are achieved.
2. Only one difference b/w our system and those in Ships is
they have unearthed system. Here phase voltage is the
voltage b/w phase and neutral OR earth. Since ships are
unearthed phase voltage is b/w phase and neutral.

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.
