>:(  that's mean KVA, and what is the property that is measured by this unit???????

 Ok thank you very much

The symbol kVA stands for kilovolt ampere. A unit of electrical load.

Here is the definition of volt ampere:

volt ampere (V·A)
a unit of electrical load used in power engineering. In an alternating current circuit, if the potential (measured in volts) and the current (measured in amperes) vary in phase with each other, then the power delivered (measured in watts) is the product of the potential and the current. In actual circuits, the potential and current are usually out of phase, causing the device receiving the power to draw more current than its wattage requirements would suggest. The product of the potential and the actual current is the load, in volt amperes.

Ahh oh then KVA is a measure of electric power jus a Hp or Watts?????
Please robert answerme please!!!!

It's a unit of load, not power.  Just a slight difference.

Power = Voltage * Current
Load = Voltage * Actual Current

This is only for AC circuits, notably power supplies and AC adapters.

That is about the limit of my knowledge on the subject.  We will need a Power Engineer to make it less confusing.
