Answer Posted / d.h.waiker
Harmonics are generated in electrical A.c systems due to
non-linear loads. There are even harmonics multiples 2,4.6
etc and odd harmonics multiples of 3,5,7 etc. There are
current Harmonics as well as voltage Harmonics .These
Harmonics will cause un necessary heating in th electrical
equipments resulting the to fail prematurly.Bad effects of
Harmonics are mitigated by harmonic filters ( Active or
paasive filters ). Active filters generates Harmonics of
oppsite polarity to system Harmonis to nullify the effects
where paasive filters give low impednace path for for
Harmonics. ( Filter is nothing but combinatoion of
capacitor and inductor to create least rsistive path for
Harmonics )
