A (different) company has an average load of 30 kVA at 0.7 power factor (lagging) connected to the 230 V, 50 Hz single phase supply. What is the magnitude of the current drawn from the supply? What capacitance is required to bring the overall power factor to 0.95 (lagging)? With the above capacitance included, what would be the new magnitude of the current drawn from the supply? By what proportion would the inclusion of the capacitance reduce the losses in the supply line?
