Reactive power beer analogy
WebSep 19, 2015 · That's the mechanical analogy for pure reactive power system - in this case a LC circuit, where energy is exchanged between an inductor and a capacitor. In a single-phase power system, reactive power comes from the interaction of generator windings and any inductive loads on the system, and it's bad because then you have this energy exchange ... WebDec 10, 2003 · Reactive Power. Q=VISinΦ in reactive kVAR. Q is the power discharged in the inductive elements of the device or circuit. Equation 3. Apparent Power. S= √( P in kVA. S is the vectorial sum of the active power and reactive power. Equation 4. Power factor. pf=CosΦ=P/S. pf is a unitless number between 0 and 1. Why compensate reactive power?
