reactive energy cannot truly reflect the status of reactive energy, whereas
4-quandrant reactive energy measuring gives a true picture of energy exchange.
Reactive energy in four quadrants represents four different reactive energy (see
Figure C-7). And the reactive energy is accumulated depending on which
quadrant it is located.
