cost of 630kVA transformer
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
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.
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'.
ka of mccb=transformer(KVA)x100/1.732xsecondary voltagex%impedence of transformer
A 10 mm cable is most commonly used for a 500 KVA transformer, 240 volt, 3 phrase. The size of the wire that is used in a transformer is based on the voltage.
The 3 kVA transformer will weigh double the 1.5 kVA transformer.
Depends on the kva rating of the devices to be tested using a transformer.
In 1600 kva transformer we provide NGR (Neutral grounding resistance)

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.
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 kVA ratings can be different and thus affect the rated current through the transformer.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.
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.
Much to my dismay i found its an experimental value, depends on type of core, cooling tech, resistance of wiring etc.
VA or KVA or MVA
