Answer Posted / gopal
HT CURRENT
I=LOAD/VOLTAGE
I=2500X1000/33*1000=75.75A
LT CURRENT
I=LOAD/1.732*433
I=2500*1000/1.732*433=3333A
OR USE SIMPLE FORMULA
1=LOAD X 1.4

WHAT IS THE FORMULA FOR CALCULATING CURRENT RATING(DIRECT IN GROUND OR AIR) OF ARMOURED(XLPE) CABLE OF 4C,16Sqmm?
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.
