If i have two 3000 kW motors and the whole facility requires
a 10 MVA transformer.
What would be better installing two 5 MVA transformers(one
for 1 motor ) or just a single 10 MVA transformer for both
of them.
Give reasons for your answer.

3000KW MOTOR 8MVA TRANSFORMER IS SUFFICIENT AND U CAN
PREFER 8MVA TRANSFORMER WITH TWO SECONDARY
WINDING(STAR,DELTA)IT WILL REDUCE UR NOISE AND HARMONICS ALSO

Answer / k.prakashchandra
It is better to have 2x5 MVA.If one of them fails or
maintenance work is to be taken up ,you can use one of the
motors.

i seen a 132kv/11kv transformer,and thier is a sugar factorys 10MW EXPORT PLANT,MY QUESTION IS THAT WHEN THEY EXPORT ELECTRICITY THEY USE THE SAME TRANSFORMER AND THE CONNECT IT TO 132/11KV TRANSFORMERS SECONDARY SIDE CAN ANY ONE EXPLAIN IT.. THE TRANSFORMER IS OF KIRLOSKAR MAKE AND IT HAS TAP CHANGER.
