    Apparent‚ and Reactive Power According to Chipkin (2009)‚ we could think of Real Power as useful power – a measure of how much work is being done. Apparent Power is the power delivered by a power source to a load like a motor. They also stated that you need to supply more power (Apparent Power) to a device than it will do the work (Real Power). Reactive Power is the (vector) difference between Apparent Power and Real Power. Reactive Power cannot be harnessed to do useful work. Power Quality Disturbances

    1. Introduction to Power Engineering 1.1 Power System Functions The traditional power system is arranged as a hierarchy. Generators feed into a high voltage transmission system that facilitates bulk transfers of power over large distances. Connected to the transmission system are medium voltage distribution networks that take power from grid supply points and deliver it to the customers who are supplied a low voltage. For a lot of its history‚ the electricity supply industry has operated as
