Ama-Harmonics avela kaningi ekuphileni kwethu kwansuku zonke.Okuvame kakhulu ukuthola ukuba khona okuphezulu kwama-harmonics ngokuvamile ezibhedlela, amanyuvesi, izikhungo zikahulumeni, izikhungo zezitolo, amalabhorethri, izimboni ezisindayo, umsakazo, i-TV, ukusakaza, imboni yokudla, ihhotela nekhasino, imboni ezenzakalela kakhulu, izindawo zokuhlanza amanzi.Okuningi kakhulu izinto ezivamile ezikhiqiza i-harmonic ezihlanganisa: ukushintsha izinsiza zamandla, ama-welders, ama-Ups, isiguquli esidala se-frequency esinobuchwepheshe bokuguqula amandla e-thyristor, amadrayivu ezimoto, iziguquli ezinama-rectifiers alawulwayo, isilawuli se-DC samadrayivu e-DC, ohhavini bokungeniswa.
Imiphumela eyinhloko ye-harmonics ilandelayo:
1.Ukushisa ngokweqile nokudlidliza okuhambisana nokuguga ngaphambi kwesikhathi kwazo zonke izingxenye, okunemiphumela yesikhathi esifushane nemaphakathi esikhathini sokuphila.
2.Amaphutha ezintweni zikagesi zikagesi.
3.Ukulimala kwezingxenye zebhodi lesifunda eliphrintiwe.
4.Electric motor overload.
I-5.I-capacitor yokuguga ngaphambi kwesikhathi kanye nokulimala ngenxa ye-resonance.
6.Ukunciphisa isici samandla.
7.Ukugcwala ngokweqile kwentambo engathathi hlangothi.
8.Ithonya likagesi.
9.Amaphutha okulinganisa kumamitha wamandla.
10.MCCB kanye nephutha lokuphazamiseka koxhumana naye.
11.Ukukhubeka okungalungile kweswishi.
Izihlungi ze-harmonic ezisebenzayokungamadivayisi ekhwalithi yamandla ahlinzeka ngokushintshashintsha kwamandla amanje alawulwayo anobude obufanayo ne-harmonic current, ejovwe ngokuphikisana nama-harmonics kunethiwekhi.Lokhu kuzoqeda amandla e-harmonic ohlelweni lukagesi.Ngenxa yalokho, okwamanje okunikezwa umthombo wamandla kuzohlala kuyi-sinusoidal njengoba ama-harmonics azokhansela ngaphandle futhi ukuhlanekezela kwe-harmonic kuzokwehliswa kube inani eliphansi kakhulu.
Izihlungi ezisebenzayoingafakwa noma yikuphi kunethiwekhi futhi inikeze izici eziningi:
1.Susa wonke ama-harmonic currents kuze kufike ku-oda lama-50 kusuka emithwalweni engaqondile.
2.Compensate amandla asebenzayo futhi ulungise isici samandla.
3.Compensate for flicker okubangelwa amandla asebenzayo.
I-Noker Electricisihlungi samandla asebenzayoyamukela ubuchwepheshe obusezingeni eliphezulu obusezingeni eliphezulu, obunezici zosayizi omncane, ukuminyana kwamandla aphezulu, ukusebenza okuzinzile nokuthembekile, okuthandwa ngamakhasimende.Ingakwazi ukwenza ukuphatha okuvumelanayo, isinxephezelo samandla asebenzayo, futhi ingenza ukubusa kwe-harmonic + amandla asebenzayo. isinxephezelo, imvamisa ye-harmonic isuka koku-3 kuye kwangama-50, ingakhuphula ukwenziwa kahle kwekhwalithi yegridi yakho.
