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.

How much oil is in a 2000 KVA transformer?
How long's a piece of string? It obviously depends on how big the transformer is!
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
How do you earth in the 1600 kva transformer?
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Why 1000 kva transformer will call 1 mw?
A 1000 kVA transformer is often referred to as 1 MW because the power factor is typically considered to be 1 (or unity) in such calculations. In electrical systems, kVA (kilovolt-amperes) measures apparent power, while MW (megawatts) measures real power. Since 1 kVA is equal to 1 kW when the power factor is 1, a 1000 kVA transformer can deliver up to 1000 kW or 1 MW of real power under ideal conditions. However, in practical applications with a power factor less than 1, the actual real power delivered may be less than this maximum.
What is the capacity 0f 100 KVA electric transformer?
KVA means thousands (K) of volts (V) times Amperes (A). A 100 KVA transformer can deliver 1000 amps at 100 volts or 500 amps at 200 volts etc.
How do you Convert va to kva?
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
How many amps will a 250 kVA transformer in 220 volts secondary?
To calculate the amperage in the secondary side of a transformer, you can use the formula: Amps = kVA / (Volts x Sqrt(3)). For a 250 kVA transformer with a 220-volt secondary, the amperage will be approximately 660.4 Amps.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.

What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
How much water will absorb transformer oil if 500 kva Transformer oil is kept exposed to moiasture?
none

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.
How much will be the oil temperature and winding temperature of 750 KVA transformer?
It depends on the load
