Sezvo akawanda uye akawanda emagetsi emagetsi anoshandiswa nhasi akawedzera zvakanyanya, chikonzero chikuru chekuumbwa kweharmonics chinoita senge ichi chaunga chemidziyo.Mune mamwe mazwi, kana isu tichizobvunza kuti nei harmonics ichiitika, chikonzero chikuru chakarara pano ihwo hupenyu hwazvino.Uye zvakare, kushandiswa kwemaitiro emazuva ano ekushandura simba neiyo iri pachena inowedzera nhamba yemidziyo inogadzirawo harmonic ikozvino.
Nekudaro, izvi hazvigoneke nguva dzose sezvo magetsi eDC ari kuwedzera kufarirwa.Kunyange kushandiswa kwakapararira kwemwenje we LED, kunyanya munzvimbo dzevanhu uye zvivako, zvinokonzera harmonic current.Kana tikaunganidza zvese izvi, tinogona kutsanangura yazvino harmonic sezvinotevera: sinusoidal mafungu kunze kweiyo yakakosha yakajairika wave inovhiringidza voltage.Mafungu eSinusoidal anoonekwa seazvino harmonic uye nhamba huru yemidziyo muhurongwa inogona kuva chikonzero chikuru cheizvi.
Mune mamwe mazwi, kuumbwa kwezvikamu zve harmonic muhurongwa haisi mamiriro ezvinhu anodiwa mumagetsi emagetsi.Mitoro yakasiyana inogona kukonzera izvi, asi inoda kuyerwa kuongororwa uye kudzivirirwa.Neimwe tsananguro, harmonic izita rehunyanzvi rakapihwa kuparara kwemagetsi nenzira yezvivi.Nhasi mamiriro ezvinhu aya anogona kuitika nyore nyore muhurongwa huri pasi pemutoro wakawanda, kureva kuti, inowanzoitika.
Panyaya iyi, zvave zvakakosha kungwarira uye kudzivirira.Semuenzaniso, makadhi emagetsi, motors uye vatyairi, zvisingagoneki magetsi emagetsi, marambi efluorescent angave akawandisa kune system.Saizvozvowo, nenzira yakapfava, harmonics inoumbwa apo nhamba huru yemakombiyuta uye midziyo yatataura pamusoro apa inosangana.Izvo zvinodikanwa kutora matanho ehunyanzvi kudzivirira kuumbwa kweharmonic uye kuchengetedzwa kubva mukukuvadza kwayo.Zvikasadaro, ma transformer anowedzera kupisa, zvishandiso zvinogona kukuvara uye mains voltage inodzikira zvakanyanya.Nekuonekwa kwezviratidzo zvakadaro mumamiriro ezvinhu akafanana, kuwandisa kunoita kuti pave nenjodzi huru uye dziviriro dzinodiwa zvakanyanya.
Kushandiswa kweNoker Electricinoshanda simba sefa, inogona kusefa iyo harmonic ikozvino muhurongwa, kuvandudza simba chinhu chegadziriro, uye inogona kugadziridzwa kune matatu-chikamu chisina kuenzana sisitimu, chishandiso chakanakira kuvandudza kunaka kwemagetsi.
