Why are there harmonic frequencies on the electricity grid? Understanding of the frequency content of signals makes us identify the individual harmonic frequencies and what they can be attributed to in the electrical installation. Harmonics is the most difficult to understand in power quality and this course is a good start for a beginner. It briefly describe what generates the harmonious voltages and some of the challenges there are present on the electricity grid. After having completed the course, it can be accessed for review individual parts.
