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.
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
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
To determine the transformer rating in KVA for a 55 kW motor, you can use the formula: KVA = KW / Power Factor. Assuming a typical power factor of 0.8 for motors, the calculation would be KVA = 55 kW / 0.8 = 68.75 KVA. It's advisable to round up, so a transformer rated at 75 KVA would be appropriate to ensure adequate capacity.
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Yes you could use a 20 kva transformer in a home. Stymied as to why it would be done though. You would need at least a 100 amp service to the home to energize the transformer. Primary side of the transformer would draw 83 amps at 240 volts. If the question was to supply the home, again yes. It would be 100 amp service equipment that the transformer would feed into.
transformer action doesn't depend on power factor that is why we indicate its rating in KVA

The 3 kVA transformer will weigh double the 1.5 kVA transformer.
To determine how many 120-volt, 7-amp lights can be run on a 15 kVA transformer, first convert the transformer capacity to watts: 15 kVA equals 15,000 watts. Each light draws 120 volts * 7 amps = 840 watts. Dividing the transformer capacity by the wattage of each light gives 15,000 watts / 840 watts per light ≈ 17.86. Therefore, you can run a maximum of 17 lights on a 15 kVA transformer.
The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
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.
