WebAug 2, 2024 · Φ is the phase angle in degrees. The larger the phase angle, the greater the reactive power. Cos (Φ) = P/S = W/VA = power factor, p.f. Sin (Φ) = Q/S = VAr/VA. Tan (Φ) … WebJun 1, 2015 · The power factor ( Fp) is the ratio of active power to apparent power: ( Eq. 1 ) The power factor is "leading" in loads that are more capacitive and "lagging" in loads that are more inductive (e.g., motor or transformer windings). In a purely resistive load, Fops = 1 (unity), such that Pa = Pap (kW = kVA) and no reactive power is present. WebA lagging power factor signifies that the load is inductive, as the load will “consume” reactive power, and therefore the reactive component Q is positive as reactive power travels through the circuit and is “consumed” by the inductive load. reginald chapman jr stuart florida
