how we can select a transformer based on a particular load.
suppose we have 4 motors of rating 40 h.p , 50 h.p, 80 h.p
& 100 h.p. then what rating of transformer we can select.
urgent. pls reply

Answer / mayank goel
Loading on Transformer 85%=337KVA
So we can use 400KVA transformer for this motors is okey.

Answer / eng. ahmed esmail
total HP = 40 + 50+80+100=270HP
total Kw =201.42Kw
at 0.75 power factor
P= S *P.F
at 0.85 transformer loading
so we will use 400 KVA transformer for this motor loads

Answer / ramesh behera
Here the g0hpiven motor values are
so total HP of motors are
1hp = 746watt
Some power in hand so we should use 260kva single phase
transformer for these motor load
