related side effects (conductor overload, circuit breakers and machines, phase unbalances,
interferences in electronic units, RCCB trips, etc.).
The level of harmonics is usually measured with the total harmonic distortion rate (THD), which
is the ratio, usually as a %, of the RMS value of the harmonic content and the value of the fun-
damental component.
