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 Posted / mayank goel
40+50+80+100
=270HP
1 HP=746Watt
270HP=201.42KW
Power Factor@.7=287KVA
Loading on Transformer 85%=337KVA
So we can use 400KVA transformer for this motors is okey.

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
