What are harmonics in electricity ?
Harmonics are currents or voltages with frequencies that are integer multiples of the fundamental power frequency,
which in the U.S. is 60 Hertz.
which in France is 50 Hertz.
If the first nammed fundamental frequency is 60 Hz, then the second is 120 Hz, and the third is 180 Hz.
Here are a few examples of issues that might be related to harmonics.
Flickering lights are a common symptom of a power quality issue.
Overheated transformers and tripped breakers could be a sign of harmonic issues.
