The symbol, kV.A (not 'KVA'!) represents 'kilovolt amperes', and is a multiple of the volt ampere, used to measure the apparent power of an a.c. circuit, that is the product of supply voltage and load current.
Apparent power (expressed in volt amperes) is the vectorial sum of a load's true power (expressed in watts) and its reactive power (expressed in reactive volt amperes).
What else can I help you with?
How can you convert the kva rating into kw rating?
kva*cos(phase angle)
If generator is 635 KVA what is alternator KVA rating?
635kva
What is the KVA rating required of the testing transformer?
Depends on the kva rating of the devices to be tested using a transformer.
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.
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.
Transformer rating is expressed in?
VA or KVA or MVA
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
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 rating in KVA for a desktop computer?
If a device doesn't give its power rating in kVA (or VA), then it can be calculated pretty easily: (volt-amperes) VA = V (voltage) x A (maximum amperage) (kilovolt-amperes) kVA = VA (volt-amperes) / 1000
What would be the kva for a heat pump?
The kVA (kilovolt-ampere) rating for a heat pump depends on its capacity and efficiency. To calculate the kVA, you can use the formula: kVA = (kW / Power Factor). A typical residential heat pump may range from 3 to 10 kVA, depending on the size and efficiency ratings. It's important to check the manufacturer's specifications for the specific heat pump in question to obtain the accurate kVA rating.
How can you calculate the rating of generator to connect with ATS 3Ph 600A 600V?
Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 KVA Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 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.
