WebApr 7, 2014 · Reactive power transfer formula In this formula, we assumed that X >>R, and thus R = 0; the formula shows a MVAR value of -4.1 MVAR, which means that the reactive power is flowing from E2 to E1; and these results don’t agree with the +5 MVAR shown in figure 2. MVAR is a function of the voltage.
WebReactive power is a critical component of AC power systems, and it plays a crucial role in sustaining the magnetic and electric fields of inductors and capacitors.
