A 415V, 50 Hz three phase supply supplies three balanced loads which draw a total apparent power (S) of 38 kVA at a power factor of 0.78 lagging. The three loads are as follows: LOAD 1 (STAR): 10.6 kVA at a power factor of 0.57 lagging; LOAD 2 (DELTA): 20 kW at a power factor of 0.53 lagging; LOAD 3 (DELTA): ZRW = ZWB = ZBR (Balanced unknown) Determine the following: i) The STAR capacitance in both kVAr and microfarads to correct the over all supply power factor to 0.85 lagging. [4 Marks] ii) Draw the power triangle with PF correction [2 Marks] iii) The total line current drawn from the three phase supply before and after power factor correction; [2 Marks] iv) LOAD 3 apparent power kVA
