Active power is the energy supplied to run a motor, heat a home, or illuminate an electric light bulb. Reactive power provides the important function of regulating voltage.If voltage on the system is not high enough, active power cannot be supplied.Reactive power is used to provide the voltage levels necessary for active power to do useful work.Reactive power is essential to move active power through the transmission and distribution system to the customer .Reactive power is required to maintain the voltage to deliver active power (watts) through transmission lines.Motor loads and other loads require reactive power to convert the flow of electrons into useful work.When there is not enough reactive power, the voltage sags down and it is not possible to push the power demanded by loads through the lines.”

Zero reactive power means the transmission line is purely resisitive which is practically not possible, even though if it happens there will be no losses in transmission
