Electric power = active power + reactive power
A generator set independently produces electricity of different power levels. This power is said to be apparent or true and is the trigonometric sum of the active and reactive power.
The reactive power required for systems equipped with a winding
Reactive power is not really power strictly speaking since one cannot “work” with it. On the other hand, it is generated by many systems or equipment, especially those equipped with a winding :
- rotating motors,
- refrigeration devices,
- some computer components
This power must then be dissipated lest your electricity provider overcharge you.
The reactive load bank to correct reactive power
This reactive power can be compensated by capacitor banks . Indeed, they have the property of being able to supply reactive energy to the system when it needs it. This is where the load bank comes in by:
- correcting reactive power
- regularizing the cosine Phi , that is, the power factor.
