Hi there.
I am a total noob when it comes to math.
Can somebody please tell me how I can calculate Kilo Volt Ampere?
I have 230 V
I have 10 A
I have 2300 W
How can I get this to Kilo Volt Ampere??
Can anyone help me plz....
Yours truly
Johndoemalle

It's actually quite easy assuming single phase wiring. VOLTS x AMPERES = KILOVOLT-AMPERES (kVA) 1000 So.... 230 VOLTS x 10 AMPERES = 2300 VA 2300 VA \ 1000 = 2.3 kVA
Hope that helps. 
btw, if it is Three Phase power use this.... VOLTS x AMPERES x 1.73 = KILOVOLT-AMPERES (kVA) 1000

Hi there.
Volt * Ampere gives WATT.. not VA.... :S
Damn i an stupid when it comes to this | |

VOLTS x AMPS = WATTS in DC, however in AC the volts and amps are not exactly in phase and WATTS needs to be calculated by multiplying the VOLTS X AMPS and then take the average over time. The ratio between the VA (i.e. rms volts times rms amps) and Watts is called the power factor PF.
VA X PF = Watts (any load, including inductive loads)
For resistive loads VA and WATTS in AC are nearly identical.
Regardless the formula to calc your Kva is correct.
