A source with 200 Vrm, 50 Hz is connected to loads as shown in Figure 2. The loads can be described as follows: Load 1: P, = 100 w, power factor = 0.53 leading Sz = 150 VA, power factor = 0.6 lagging Load 3: P3= 50 W, Q, = 120 VAR (inductive) Load 2: a) Draw and label the power triangle diagram for Load 1, Load 2 and Load 3. b) Find the overall complex power delivered to the load. c) Find the supply current, I,. d) Determine the overall power factor of the combined load. e) Determine the value of the capacitor that should be added at terminal A-B to improve the power factor to 0.99 lagging. [Hint: Draw the power triangle diagram] Load 2 200 Vms Load I Load 3 50 Hz
