It depends on the transformer design, type, cooling, maintenance, fault experiences, operating temperature, and loading (I'm sure there's other things that impact it as well). A lot of equipment is rated for 10-20ish years of operation; I would assume your transformer may fall under that. That does not mean that it is dead after 20 years though; I know of several >10MVA Transformers that are 60+ years old and still in use. Some have been rewound, some have not. And it doesn't mean that it is 100% guarunteed to run for 20 years. A really bad fault with slow clearing time could cook it the day after you install it.

No. Assume the best-case, that is, the load has a power factor of 1.0 (unity). Convert each figure to watts: 110 kva = 110,000 watts 1000 kw = 1,000,000 watts It is apparent that the load requires 9 times the power the transformer can supply, even more if the power factor is less than unity.

It depends what you mean by 'total current'. Do you mean its 'rated secondary current'? Or do you mean its 'load current?'

If you mean its 'rated secondary current', then you must divide the rated volt amperes by the rated secondary voltage. If you mean its load current, then you must divide its rated secondary voltage by the impedance of the attached load.

In a step up transformer how does the current drop if the voltage rises?

Transformers are rated in KVA, both the primary and secondary windings have the same KVA rating. (KVA is the voltage multiplied by the amperage then divided by 1000). If you have a 10 KVA step up transformer with 120V on the primary: A = 10k / 120 = 83.33A and if the secondary produces 240V: A = 10k / 240 = 41.667A

Why you are indicating capacity of transformer in KVA?

transformer action doesn't depend on power factor that is why we indicate its rating in KVA


What is the result when 3 kva power requirement is being supplied by 250 kva transformer?

The result is that the transformer runs cool and contented. The '250 KVA' rating on the transformer is its maximum ability to transfer power from its input to its output without overheating, NOT an amount of power always running through it. If the 3 KVA load happens to be the only thing connected to the transformer at the time, then only 3 KVA flows into the transformer from the primary line, and only 3 KVA leaves the transformer secondary.
