Reactive power calculation formula
WebApparent Power in an AC circuit is the resultant of the active and reactive powers. In complex number, S = P + j Q. Where the S is the apparent power, P is active power and the Q is reactive power. Active Power or True power, P = V x I CosΦ W Reactive Power, Q = V x I SinΦ VAR Apparent Power, S = V x I VA WebReactive power (KVAR) required by inductive loads increases the amount of apparent power (KVA) in your distribution system (Figure 4). This increase in reactive and apparent power results in a larger angle θ (measured between KW and KVA). Recall that, as θ increases, cosine θ (or power factor) decreases. KVA KVAR KVA KVAR θ θ
