3 1 kVA is 1000 VA. Apparent power is measured in VA which is a reactive (i.e. a mix of both
capacitive and inductive) load’s RMS voltage multiplied the RMS current. True power is VA
multiplied by the power factor, and the power factor is the cosine of the phase angle between
voltage and current. A reactive load that draws an apparent power of 1000 VA and has a 0.5
power factor is consuming 500 watts of power. If a device were purely inductive, it would
have a power factor 0. See also footnote 2, on page 4.
