Hai I have 2500KVA,Transformer,13.8KV/380.DELTA/STAR.How
much load that I can take interms of current?How can I
calculate also when I have loads in KW?
Answer Posted / shalini.b
Transformer Ratio is given by
k=(v1/v2)=(N1/N2)=(i2/i1)
where
V1 : voltage at the primary side
V2 : Voltage at secondary side
like wise for current(i)& Number of turns(N)
k= V1 /V2
= 13800/380
=36.31
P=1.73*V*i*cos(phi)
input power
p1=1.73*v1*i1*cos(phi)
i1=(2500*0.8)/ (1.73*13.8*0.8)
= 104 Amps
k = i2 /i1
So i2 = 104*36.31
=3776
