Re active energy and power harmonics explained with a car
How to understand harmonics & re active energy
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.
