Answer / sks

50*1000*.8/1.732/415/.8=69 A Per Phase

Answer / vikrant

40*1000=1.732*415*I*.8
40000=575.024*I
THERE FORE I=40000/575.024=69.562314 AMPS
THEREFOR FULL LOAD AMPS OF 50KVA DG IS=69.56 AMPS

Answer / dharam raj mali

50*7.39=69.5Amp.

Answer / nagendra kumar

actually i think that in 3 phase formula is p = ROOT3 VI COS$ AND in 1 phase formula will P = VI COS$

SO 40 *1000 = 220 * 0.8 ( if we consider voltage 220 volt in single phase) 40000 = 176 i
I 40000/176 = 227 AMP

40*1000 = 415*0.8 I( IF WE CONSIDER V 415 VOLT)

40000 = 332I
I= 40000/332 = 120 AMP
