Re active energy and power harmonics explained with a car
Are you a driver? I am sure yes, therefore you will understand power harmonics right away
Imagine a straight road, flat, a perfectly smooth surface, a constant speed. Your car works well, consumes as little as possible, and can run indefinitely.
It’s like an electrical grid with a constant power without harmonics.
testing active power ?
In an electrical circuit, the active power P is the real power transmitted to loads such as motors, lamps, heaters, computers … The electrical active power is transformed into mechanical power, heat or light.

You probably experienced reading documentation, technical papers, or even display of monitoring equipment with reactive power values (for power factor correction…) given in KVAR, kVAr, or kvar.
And you probably asked the question: which symbol should be used?
I want to share with you information about regulations and policies in different countries about power factor correction: are penalty levels specified, which levels ?
world kvar penalties : Germany, Austria, Canada, Spain, France, Portugal, ... ?
