KVA Calculator V1.0

This is a Calculator App (don't look on the App screen) that calculates electrical power, typically for industrial uses.  The basic equations for three-phase power are:

Volts * Amps * sqrt(3) / 1000 = KVA (kilovolt-amperes)
KVA * Power Factor = KW (kilowatts)
KW * efficiency / 0.746 = HP (horsepower)

For single-phase AC or DC power, the sqrt(3) factor is replaced by 1.
Also, for DC power, the Power Factor is always 1

Note that the default values for Power Factor and efficiency are nominal, and will vary greatly depending on the motor (if, in fact, the calculations are even for a motor).

Entering a value in any field will cause the remaining fields to be re-calculated using the new value.

Remember, since it's a Calculator App, start it by pressing the Calc button, pressing the black bar near the top, and selecting KVA Calc from the list.

This is FreeWare, but I'd appreciate hearing from anyone that makes any use of this program, since it is fairly specialized...
