Answer Posted / satya mahesh
load factor(LF) and utilization factor(UF) will play a
major role in transformer selection.
Connected load-4810
Maximum demand in a month-1582 Amps
Average load which will be the average of running loads
came in a month-1173 Amps
LF=average load/max demand
=1173/1582
=0.74
UF=No.of hours running Equip/total hours in a month
=(30*20)/(30*24)
=600/720
=0.83
Transformer size= Connected load X LF X UF
=4810 X 0.74 X 0.83
=2954 Amps
for 2954 Amps 2500 KVA(3484 Amps) transformer was suitable
in continution to the future loads also.
