Electrical loads such as motors can cause electrical systems to be very inductive, which results in very ‘lagging power factor’ i.e. wastage of energy. The simple solution to maintain the power factor in required range is to connect or disconnect the power factor correction capacitors. Manual switching is just impossible for rapidly fluctuating loads and hence an automatic control system is required which continuously monitors the power factor and make appropriate corrections to maintain it within the required range.
