A big one - one that can supply thousands (k) of V.A (not kva, but kV.A).
AnswerA volt ampere is used to measure apparent power (the vector sum of true power and reactive power. Transformers are rated in volt amperes, rather than in watts because to rate transformers in watts, it's necessary to know the power factor of the load, and transformer manufacturers have no way of knowing that.A kilovolt ampere (kV.A) is one-thousand volt amperes. Distribution transformers are typically rated in kilovolt amperes. For example, pole-mounted distribution transformers are typically 5 kV.A, 50 kV.A, etc., and are used to reduce high-voltages to residential low voltages.
Power transformers, used on transmission systems, are usually rated in megavolt amperes.
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
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.
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 amps you can get from a 500 kVA transformer would depend on the voltage of the transformer's output. To calculate amperage, you can use the formula: Amps = Power (kVA) / Voltage. For example, if the output voltage is 480V, you would get approximately 1041 amps (500 kVA / 480V).
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 3 kVA transformer will weigh double the 1.5 kVA transformer.
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Depends on the kva rating of the devices to be tested using a transformer.
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
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.

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.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
You can tap off approximately 833 200 amp panels from a 250 kVA transformer. This calculation is based on dividing the kVA rating of the transformer by the current rating of the panel.
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.
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.
