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
What else can I help you with?
How do you earth in the 1600 kva transformer?
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
Why transformer rating is called kva not kw?
Transformers are rated in KVA because that is a more accurate way to measure their capacity requirements. KWH is apparent power, while KVA is true power, and the ratio between them is power factor. The power factor is a function of the load, and not the transformer, so a poor power factor would make KWA look less to the transformer while, in fact, the true power, if not met by the transformer, could overload the transformer.
Transformer rating is expressed in?
VA or KVA or MVA
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
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 do you earth in the 1600 kva transformer?
In 1600 kva transformer we provide NGR (Neutral grounding resistance)
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.
Cost of 630 kva transformer in rupees?
cost of 630kVA transformer
480 transformer to 120 ac current what is the kva on transfomer?
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.
Do the load carried by a transformer is affected by KVA rating?
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
How many 200 amp panels can you tap off 250 kva transformer?
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.
Why transformer rating is called kva not kw?
Transformers are rated in KVA because that is a more accurate way to measure their capacity requirements. KWH is apparent power, while KVA is true power, and the ratio between them is power factor. The power factor is a function of the load, and not the transformer, so a poor power factor would make KWA look less to the transformer while, in fact, the true power, if not met by the transformer, could overload the transformer.
What is the same on both sides of any transformer?
frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.
Can you use a step up transformer 110220 with output of 16 kva?
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.
