How do you calculate kw in three phase generator?

Use the following equation, kW = Amps x Volts x 1.73 x pf/1000.


How many amps is 55kw at 460 volts?

To calculate the amperage, use the formula: Amperes = Watts / Volts. In this case, 55 kW is 55,000 watts. So, Amperes = 55,000 watts / 460 volts ≈ 119.57 amps.


Calculate 75amps and 440volt what is the value in kW?

The formula you are looking for is W = I x E. Watts = Amps x Volts divided by 1000.


How many BTU does kW electric heater put out running at three phase 465 volts?

Not enough information. You didn't specify the amount of kW - and you really can't calculate that, just from the volts. Once you know the amount of kW (which is a unit of power), you still need to multiply by time to get energy. Then you can do the appropriate conversion to BTU, which is also an energy unit.


How do you calculate amp draw if you have 1 phase volts and kw?

For a single phase supply: you need to know the volts, kW and the power factor. If the power factor is unknown, assume 0.75, except for heating elements which have a power factor of 1. Multiply the kW number by 1000 then divide by the voltage. The answer should be divided by the power factor to find the current in amps.


How many amps will a 500kw using 240 volts produce?

To calculate the amperage, you can use the formula: Amperes = Watts / Volts. So, for a 500 kW system at 240 volts, the amperage would be 2083.33 Amps.


How many kw are being used in a 10 ohm resistror if 120 volts where applied to it?

1.44 kw


How many volts in kw?

Volts and Kilowatts are different. no comparison can be drawn in respect to a straight conversion.


If a central air conditioner uses 10 KW while running at 220 volts what amperage current does it use?

To calculate the amperage current, you can use the formula: Amperes = Watts / Volts. In this case, it would be 10,000 Watts (10 KW) / 220 Volts = 45.45 Amperes. Therefore, the central air conditioner would use approximately 45.45 Amperes while running.


What is the output of 305 KW at 240 volts switched to 480 volts?

If the power output remains constant at 305 kW, doubling the voltage from 240V to 480V will halve the current drawn by the system. This change in voltage will not change the power output; it will remain at 305 kW.


How many amps for a 13.8 kw cooker?

The formula you are looking for is Amps = kW x 1000/1.73 x Volts x pf. The pf (power factor) of resistance heating will be 1. If the cooker was rated in kVA the same formula would be used minus the pf.


How do you calculate amp with kw and kva?

I (current in Amps) = E (volts) / R (resistance in ohms) ... W (Watts) = I x E ... The k simply means 1000
