Answer / sujit288

60kva x 0.8=48kw or 48000watt
we know p=1.732xVIcos@
I=p/1.732xVcos@
I=48000/1.732 X 415v X 0.8(Where V=415v)
I=48000/575
I=83Amps

So Full load current is 83 Amps.

Answer / muralidhar k.s

Kw=1.732*V*Icos@
Kva=kw/cos@=1.732*V*I
I=1000/1.732*415
I=1.4*Kva

Full load current=KVA*1.4
The full load current for 60 Kva is 84amps.

Answer / sreenu

Rating of UPS is in KVA, Hence it is just like a
transformer or alternator.

So I(Current)= S (Apperent power)/Voltage only.

Answer / guru

i agree with answar no 1.
we know,
W=v.i.cos@
therefore first converted kva to watt then calculate fl amp.
thank's sujit for appropriate....

Answer / sathishbabu t

p=v*i*cos

Answer / rahul

Full load current =Kva*1000 /v*Powe factor

Answer / kumar

formula of 3 phase power calculation

p=1.732*VL*IL*cos@

60*1000= 1.73*440*IL*0.9 (0.9 IS WE MAINTAIN POWER FACTOR)
IL=60000/685.87
IL=87 AMPS IN EACH PHASE THIS IS 100% LOAD DONT LOAD 100%
LOAD 80%ONLY MEANS 70AMPS
