Why Do We Need Reactive Power?
* Reactive power (VARS) 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.
