Amps To Kilowatts

How Do You Determine Kilowatts From Amps? I Have 288 Amps How Do You Determine How Many Kilowatts That Is?

Re: Amps To Kilowatts

What Voltage are you assuming?

The conversion of Amps to Watts is governed by the equation

Watts = Amps x Volts

For example 1 amp * 110 volts = 110 watts

In your case I will assume 110 volts so:

288 * 110v = 31,680 volts

or

31.68 Kilowatts

Re: Amps To Kilowatts

288A * 110V = 31,680 Watt

but 288A on a 110V grid is unlikely; I would expect it is 480V in a three phase grid; that makes it even more difficult :-)

That was just an example of the arithmetic.

8 A x 220 V x 1 kW/1000 W = 1.76 kW

400amps @ 3p208

400*(3*208)=249,600w

249,600/1000=249.6

That should be 400A x sq rt 3 (1.73) x 208V = 144,106.63 W or 144.1 kW.

You have to take the square root of the phases because they don't peak simultaneously but sequentially 1/180 of a second apart.
