A 3-phase, 50Hz, 400V motor develops 100 HP (74.6kW), the power factor being 0.75 lagging and efficiency is 93%. A bank capacitors is connected in delta across the supply terminals and power factor raised to 0.95 lagging. Each of the capacitance units is built of 4 similar 100V capacitors. Determine the capacitance of each capacitor.
