How to convert kVA to kW and to Amps
Volt Ampere is the unit of apparent power, while Watt is the unit of the active power
The power triangle is the best way to remember the kVA to kW formula
As you can see the apparent power in kVA, the active and reactive power are forming this triangle
While this angle F is the power factor angle. From the power triangle, the kVA to kW formula is
P, active power in kW, equals F, in kVA, multiplied by cosine the angle between them, or the power factor
This is the kVA to kW formula. Let's have an example, but first please help me and hit the like button
If we have apparent power, F, of 50 kVA, and power factor of 0.85
P equals 50 times 0.85, equals 42.5 kW. Now let's convert to a Volt Ampere and to Amps
In this case we will have two equations, one for single phase and the other is for three phase
In the description below you will find my 100% free fast electrical calculation Android app
Install it now, it has the calculations of kVA to Amps. In case of single phase loads, the equation is
Current, I, equals apparent power, F in Volt Ampere, divided by voltage in Volts
Let me have an example. Before the example, please hit the like button. Thanks
If we have a single phase load of 10 kVA and operating voltage of 110 Volts
Then the current of this load is equals, 10,000, divided by 110 equals 90.9 Amps
Now let's convert to a Volt Ampere and to Amps in case of three phase loads
In case of three phase loads, the equation is Current, I, equals apparent power, F in Volt Ampere, divided by voltage in Volts multiplied by 1.73
It's clear that the two equations are similar except in case of three phase we multiply voltage by 1.73
Let me have an example. Could you please help me and hit the like button. Thanks
If we have a three phase load of 10 kVA and operating voltage of 208 Volts
Then the current of this load is equals, 10,000, divided by 208 times 1.73, equals, 27.75 Amps
