Complex power units
WebMay 22, 2024 · The basis for the per-unit system of notation is the expression of voltage and current as fractions of base levels. Thus the first step in setting up a per-unit normalization is to pick base voltage and current. Consider the simple situation shown in Figure 22. For this network, the complex amplitudes of voltage and current are: WebAs a rule, true power is a function of a circuit’s dissipative elements, usually resistances (R). Reactive power is a function of a circuit’s reactance (X). Apparent power is a function of …
