In short circuit test , what is the current will come in primary ,secondary. as secondary shorted. if 2500KVA,33KV/433V trafo %z 7.3 . what will be the current at secondary.
.......until the circuit protective device operates to disconnect it.

Short ckt test is a Type Test and normally done in the Manufacturer's works or in recognised Testing Labs such as CPRI,ERDA,NEMA etc. I don't understand why you want to do it yourself and measure such high current through a clamp meter.Further, note that this will also reduce the life of your Transformer.
You may ask the Manufacturer to furnish a Type Test Certificate for similar design/rating Transformer alredy done by him for your reference.

Presuming that you are an electrical engineer, I am pretty sure that in your college days, this "Short Circuit Test" on a transformer is one of the very important Lab Excercises. Did you bunk the class, when this excercise was taught to you?
Refer your text books once again and read how to perform short circuit test on your transformer. You should not apply rated primary voltage during this test.
For the transformer you have mentioned, if you apply 7.3 % of rated primary voltage to the primary winding, keeping the secondary shorted, you will find rated current flowing in both windings.
You can also search the web for transformer stability test.
