Calculating DG Set current
Calculating DG Set current
Calculation of DG set current while knowing KVA Rating -
Formula -
Power (KW) = 1.73 x V x I x Power Factor (PF)
Example - DG set of 1010 KVA with a power factor - 0.8 & Voltage 415 V
So, To calculate the DG set current first we have to calculate the power
P.F. = KW/KVA
KW = KVA x P.F.
KW = 1010 x 0.8
KW = 808
Hence,
Power (KW) = 1.73 x V x I x Power Factor (PF)
808 x 1000 = 1.73 x 415 x I x 0.8
I = 808000/1.73 x 415 x 0.8
I = 808000/575
I = 1405 Amp
So, For 1010 KVA D.G Set the maximum current capacity is 1405 Amp
