Reactive power and power factor correction essentials to …

We define the reactive power to be positive when it is absorbed (as in a lagging power factor circuit).. a. Pure capacitance element – For a pure capacitance element, P=0 and I leads V by 90° so that complex power is:. S = jQ = (V ∠0°) (I ∠90°) S = V×I ∠−90° S = −jV×I. Thus the capacitance element generates reactive power.
