A threephase, balanced load is star (wye) connected and consumes 180 kW from the grid (400Vrms@50Hz). A capacitor bank (also balanced) of 65 kVAr is connected in parallel. As a result the total power factor equals 0.90. a) Determine the power factor of the load (so without capacitor bank. b) The capacitor bank is delta connected. Determine the capacitance of the capacitors.
