II — Operating aspects of reactive power

“Reactive power” is discussed in this article from the point of view of the practical operating engineer. The direction of flow in a transmission line of this reactive power with respect to the “active” power is shown to determine whether the current lags or leads the voltage. It is urged that only one kind of reactive power (lagging) be recognized, and that its direction of flow be considered. A simplification of system operating problems is claimed to result from this view. Use of the symbol rkw is urged.
