What is Reactive Power? | Ansys
Reactive power is power that is reflected back to the grid — as opposed to active power, which is power that is consumed by the load. Similar to the pressure that pushes water through a pipe, voltage acts as the pressure that pushes electrical current through power lines. To do this, voltage draws on reactive power.
