What will be the total current for 300kva UPS if it runs on
40 to 45 percent load. Is there any formula for to
calculate the exact load.
Answer Posted / thowsif_emerson_csm team
For 300 KVA the Full load Current=KVA*PF,
i.e 300x.8=240000 Watts.
we know in 3 Phase Circuits,
P=1.732x V x I x Pf,
I=P/1.732xV x Pf,
I=240000/1.732 X 440 X 0.8,
Full Load Current, I =240000/609=394 Amps,
The Load Current @ 40% is 394*.40=158 A(Total Load Current).
The Load Current @ 45% is 394*.45=177 A(Total Load Current).
So load current at 40% Load is 39*.40=15.6 A/Phase Amps.
