The rating of a transformer follows the two magnitudes that affect its operation; Volts and Amperes. The other, more popular parameter (kW) is not used on Transformers because it depends on connected load Power Factor.
What else can I help you with?
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a 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.
What is the minimum load have to go for a new transformer?
All transformers have a power rating given in kVA which determine the maximum load that can be connected to that transformer.
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
Transformer rating is expressed in?
VA or KVA or MVA
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.
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.
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.
What is kva rating of single phase 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'.
What should be the rating of the transformer in KVA to cater to 55KW motor?
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.
How the ka rating of mccb is calculated?
ka of mccb=transformer(KVA)x100/1.732xsecondary voltagex%impedence of transformer
What is the kw of 100kva transformer and how you calculate?
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.
