Hi frnds :)
plz tell me that i have 100 KVA 3 phase generator so by
thumb rule 100*1.4 = 144 amps
and generaly we can operate at 80% load...so it will 144*0.8
so now i m confused about single phase load.....if we use
that generator only for single phase the that 112 amps is
total single phase load or i can give 112 amps at red 112
amps at yellow and 112 amps at blue....
i mean that total single phase load that 100 KVA generator
will take is 112+112+112=336 amp ??
Need your help for connecting APFC panel,
Quotation : I have 2 Noâ€™s 1000 KVA Transformers, both transformers are having separate APFC panels, ( Tr-1,400KVAR, TR-2,450 KVAR)
Now I want to stop One transformer, present load is 650Amps, Max, So One transformer is enough, I have switched OFF TR-1, but PF is not maintaining properly, its 0.5, So now I want to connect TR-2 APFC also in TR-1 Loads, Can any one answer for my Quotation with drawing, how to connect TR-2 APFC panel in TR-1 Loads,
