Determine(i) rating of capacitor bank kVAR,(ii) capacitance of each unit, if they connected as (a) delta, and (b) star, in uF.7. Figure 1 shows the electrical power system with rated capacity of S₁= S₂=25 MVA,connected with two step-up transformers 11 kV/66 kV, respectively. The shortcircuit fault at point 'p' occurs at the outlet of transmission line.
