is harmonic useful or it distort the alternating quantity?

Answer Posted / guest

It is harmful.Blown-fuses on PF correction caps, due to
high voltage and currents from resonance
with line impedance.
- Mis-operation or failure of electronic equipment
- Light flicker results when there are voltage subharmonics
in the range of 1-30Hz. The
human eye is most sensitive at 8.8Hz, where just a 0.5%
variation in the RMS voltage is
noticeable with some types of lighting.
