Description
Volt-Ampere
(VA)
A rating of apparent power (i.e., the amount of AC power that is
available to or can be handled by utility equipment) measured
with a volt meter and an ammeter. In single-phase systems VA = E
× I, where E
= volts, I = current in amperes. In three-phase
systems VA = 1.73 × E × I.
Watt (W)
A rating of true power consumed by the product and measured
with an input power meter. In single-phase systems W = E x I x pf,
where E = volts, I = current in amperes, and pf = power factor.
