What will be the average KVA rating of Auto Transformer
for 75kw 415V , 3phase induction motor
Answer Posted / baikunth
motor rating in kva = 75/0.5=150kva
so the apparent power is let 200kva.
Keeping the starting condition and fault conditions like
overload,single phasing etc. I suggest 200x3=600kva or
750kva a standard value for the motor of 75kw,supposing that
transformer ration is 1:1.

ii) A shunt motor supplied at 230V, runs at 900 rpm when the current is 30A. The resistance of the armature is 0.4 ohms. Calculate the resistance required in series with the armature to reduce the speed to 600 rpm, assuming that the armature current is then 20A. [12]

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?
