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.

What is the kva rating of a transformer that has a secondary winding that's delivering 10 amps at 480 vac?
To calculate the kVA rating of the transformer, you can use the formula: kVA = (Voltage × Current) / 1000. In this case, the secondary winding delivers 10 amps at 480 volts. Therefore, the kVA rating is (480 V × 10 A) / 1000 = 4.8 kVA.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.
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
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.
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
What is the kva rating of a transformer that has a secondary winding that's delivering 10 amps at 480 vac?

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.
How many amps can a 0.50 kva transformer give 277v input 120v output?
To determine the output current in amps for a 0.50 kVA transformer with a 277V input and 120V output, you can use the formula: Power (kVA) = Voltage (V) × Current (A) / 1000. For the output at 120V, the current would be calculated as follows: 0.50 kVA = 120V × Current (A) / 1000, which gives Current = (0.50 × 1000) / 120 ≈ 4.17 amps. Thus, the transformer can provide approximately 4.17 amps at the 120V output.
What is the difference between a 1.5KVA and a 3KVA transformer?
The 3 kVA transformer will weigh double the 1.5 kVA transformer.

How many amps does a 55kva transformer can provide?
To determine the amperage a 55 kVA transformer can provide, you can use the formula: Amps = kVA × 1000 / Voltage. For example, at a standard voltage of 400V, a 55 kVA transformer can provide approximately 79 amps (55,000 / 400 = 137.5). The actual amperage will vary depending on the specific voltage used in the application.
