In this video I will calculate the total-power=? of a 2-load 3-phase system. Load 1 draws 30kW with a power factor, PF=0.6, which is lagging, and load 2 draws 45kVAR with a power factor, PF=0.8, which is lagging. This will require using the triangle representing the real power, P; the reactive power, Q; and the complex (apparent) power, S.
