To answer this question the voltage of the circuit must be stated. That is what the v in kva stands for.
635kva
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.
VA or KVA or MVA
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.
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.
kva*cos(phase angle)
The maximum current rating for a 20A wire gauge is 20 amperes.
635kva
Depends on the kva rating of the devices to be tested using a transformer.
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.
yah! definately affects, the kva of transformer is suitable for the certain load according to the rating.
20A.
VA or KVA or MVA
transformer action doesn't depend on power factor that is why we indicate its rating in KVA
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.
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
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.
