as while designing alternator we have to consider two ckt. i.e. electrical ckt.& magnetic ckt. and electrical ckt.is designing by considering current & magnetic by volt.thats why rating is in kva.
635kva
kva*cos(phase angle)
Depends on the kva rating of the devices to be tested using a transformer.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
VA or KVA or MVA
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
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
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
The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
Usually increase will cause the KVA levels to come up, especially when you have a decent amperage...
One horsepower is equal to 746 watts.
Transformers are rated in VA or kVA. That is because the voltage is limited by the power loss in the magnetic core, and the current is limited by the power loss in the resistance of the windings. The rated voltage times the rated current gives the transformer's rating in kVA.
