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 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.

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 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 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.


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.
