The full load of 15 Kva DG set will be 12 KW on 0.8 power
factor. if the DG set is 3 phase(415 v) then per phase
current will be I = 15000/(1.732X 415)= 20.86Amp/PHASE

Answer / sunny

for a 15 kva dg set I=15*1.39=20.85

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
