Presumably, you are asking what is the rated secondary current for a 45 kV.A (not 'kva') transformer? The answer depends on its rated secondary voltage. To obtain the rated secondary current, you divide the (apparent) power rating by its secondary rated voltage.
the capacity of a transformer is defined as a product of voltage and current flowing through it.AS THE CURRENT IS MEASURED IN AMPERES AND VOLTAGE IN VOLTS, Hence transformers are measured/rated in KVA
A: Absolutely while the voltage can be changed the current is limited by the design or kva
The load is the product of the load current and the secondary voltage. So, in this example, the load is 8 x 2000 = 16 000 volt amperes, or 16 kVA. This must not exceed the transformer's rated kVA.
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
The rating of the machine (kva or kw) depends upon the power factor, since the load power factor to which the transformer is supplying power is not known, it may be capacitive, inductive, or resistive that is why its rating is in kva not in kw.
a kva is 1000 vaK is kilo, which means 1000 similar to how a kilometer is 1000 metersTransformers are usually rated in KVA, so a 45 KVA Transformer is a 45 000 VA Transformer
The kVA rating will be listed on the transformer's nameplate, which is usually on the front of the transformer. The 480v to 120v is irrelevant, because many transformers with different kVA ratings convert 480 volts to 120 volts. The kVA ratings can be different and thus affect the rated current through the transformer.

Yes, but your input current is going to be high at 133 amps. The output of the transformer is not going to be 16 KVA, that is the rating of the transformer.
Each phase supplies 15 kVA. The primary has a line-to-neutral voltage of 277 v so the line current is 15,000 / 277 or 54 amps. The secondary has a line-to-neutral voltage of 120v so the current is 15,000/120 or 125 amps.
This is the rated output of the transformer, obtained by multiplying the rated secondary voltage by the rated secondary current. And it's 'kV.A', not 'kva'.
It depends on the rated voltage. Take 1600 KVA and divide by KV, and you will get A.

A: Absolutely while the voltage can be changed the current is limited by the design or kva
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
The correct symbol for kilovolt amperes is 'kV.A, not kva. A volt ampere is the product of the transformer's secondary rated voltage and its rated current. It is not rated in watts, because the transformer designer has no idea what sort of load is to be applied to the transformer, and it is the load that determines the amount of watts, not the transformer.
