For all of the Questions use 4 most significant digits after the decimal point (e.g.: ) 1. A three-phase load draws 720 kW from the grid with 0.8 lagging power factor. The load is balanced and star connected. For reactive power compensation, a bank of capacitors is connected in star across the load terminals. With this compensation, active power loss across the lines is reduced 10% (Meaning that If the power loss is 1 unit before compensation, power loss is 0.9 unit after compensation). Assuming that compensation does not change the load terminal voltage, calculate a) b) c) The kVAr rating of capacitors in each phase The improved power factor The new power factor if the same bank of capacitors is connected in delta Hint: The power loss across the line is proportional to the line current and hence the apparent power.
