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 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.

How many computers can you connected with a 10 kva UPS?

The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts.The number of computers a 10 kVA UPS can support depends on the power consumption of each computer. On average, a standard desktop computer with monitor uses about 300–400 watts. To estimate: 10 kVA UPS ≈ 8000 watts (assuming 0.8 power factor) If each computer uses 400 watts: 8000 ÷ 400 = 20 computers So, a 10 kVA UPS can support around 18 to 20 standard computers for a limited time, depending on the load, battery condition, and runtime required.


Why alternator rating in KVA?

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.


Is the kva rating of a three phase generator per phase or a total of the three phases example is a 3 phase 75 kva generator 25 kva per phase or 75 per phase?

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.
