aa unit of potential equal to the potential difference between two points on a conductor carrying a current of 1 ampere when the power dissipated between the two points is 1 watt; equivalent to the potential difference across a resistance of 1 ohm when 1 a 潜力单位相等与二点之间的电位差在运...

Reactive power is the power dissipated in an induc-tive or capacitive load and is measured as volt-ampere reactive (var). Reactive energy is the accumulation of reactive power over time. RP = 1 nT RPt dt = VI × sin(θ) nT 0 where: V is the rms voltage. I is the ...
Three-phase operation of outputs from a rotating machine is illustrated in FIG. 3 wherein phase windings 10, 11 and 12 are "Wye" connected, 120° out of phase. Assuming that each winding produces 1 volt and one ampere, the power per winding would equal 1 watt, and the total power outp...
