Let us consider a positive phase sequence circuit with a line voltage of 450V at 50HZ. The wye connected 50hp motor is connected as load across the three phase lines. If we want to adjust its power factor to unity, design the value of capacitor that needs to be connected to each phase. Consider that motor is working at 75% efficiency with a power factor of 0.8 lagging. Efficiency is the ratio of power output to the power input.
