What is the amount of no load current of 630 kVA tranformer
voltage ratio 11kV/440V ?
Answer Posted / gaurav srivastava
it is a tricky question....
u know that when transformer is at no load. the secondry
windings are open...so that there is no current flow at
secondry winding...
and for primery winding we calcute these value from OPEN
CIRCUIT TEST.
that is mentioned in all books thats have transformer
chapeter...

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
