A 200 KVA UPS's load current is 70 A. We want to provide a
Generator back up. What capacity of DG required for this ?

Answer Posted / laxmikant

Question is not clear,

Because 200kVA/(1.732x0.415kv)= 278.24 Amps/phase.
Please check. If you load demmand is 200kVA , as DG runs
always with 89% efficiency @ 100% load, You may choose for
250kVA DG.

Is This Answer Correct ?    2 Yes 0 No
