Reactive Power Compensation of Reactive Components
In a DC circuit, the product of "volts x amps" gives the power consumed in watts by the circuit. However, while this formula is also true for purely resistive AC circuits, the situation is slightly more complex in an AC circuits containing reactive components as this volt-amp product can change with frequency affecting the circuits reactive power.

What is reactive power and why does it matter?
If the active power demand falls below the generator''s active power output, then voltage rises, which damages the insulation of windings and can cause dangerous electrical discharges. Similarly, when reactive power generation is greater than reactive power absorption, the voltage increases, and vice versa.
