Ma Harmonics amawonekera pafupipafupi m'moyo wathu watsiku ndi tsiku.The pafupipafupi kupeza mkulu kukhalapo kwa harmonics kawirikawiri zipatala, mayunivesite, malo boma, malo kugula, zasayansi, mafakitale katundu, wailesi, TV, wailesi, makampani chakudya, hotelo ndi kasino, makampani kwambiri makina, madzi mankhwala plant.The kwambiri zida zodziwika bwino zopangira ma harmonic kuphatikiza: makina osinthira magetsi, zowotcherera, zowotcherera, Zokwera, zosinthira ma frequency akale ndi ukadaulo wosinthira mphamvu wa thyristor, zoyendetsa zamagalimoto, zosinthira zokhala ndi zowongolera zowongolera, zowongolera za DC zama drive a DC, mavuni olowera.
Zotsatira zazikulu za ma harmonics ndi awa:
1.Kutentha kwakukulu ndi kugwedezeka ndi kukalamba msanga kwa ziwalo zonse, ndi zotsatira zazifupi ndi zapakati pa nthawi ya moyo.
2.Zowonongeka pazida zamagetsi zamagetsi.
3.Kuwonongeka kwa zigawo za bolodi losindikizidwa.
4.Mota yamagetsi yamagetsi.
5.Premature okalamba capacitors ndi kuwonongeka chifukwa cha resonance.
6.Kuchepetsa mphamvu yamagetsi.
7.Kuchuluka kwa waya wosalowerera.
8.Chikoka chamagetsi.
Zolakwika za 9.Measurement pamagetsi amagetsi.
10.MCCB ndi kusokoneza contactor kulakwa.
11.Kudumpha kolakwika kwa switch.
Zosefera zogwira ntchito za harmonicndi zida zamtundu wamagetsi zomwe zimapereka mphamvu zowongolera zomwe zimakhala ndi matalikidwe ofanana ndi apano, omwe amabayidwa motsutsana ndi ma harmonics pamaneti.Izi zidzathetsa mphamvu ya harmonic mu dongosolo lamagetsi.Zotsatira zake, zomwe zimaperekedwa ndi gwero la mphamvu zidzakhalabe sinusoidal monga ma harmonics adzathetsa wina ndi mzake ndipo kusokonezeka kwa harmonic kudzachepetsedwa kukhala otsika kwambiri.
Zosefera zogwiraikhoza kukhazikitsidwa paliponse pa netiweki ndikupereka zinthu zambiri:
1.Chotsani mafunde onse a harmonic mpaka ku dongosolo la 50 kuchokera ku katundu wopanda mzere.
2.Compensate mphamvu yogwira ntchito ndikuwongolera mphamvu yamagetsi.
3.Compensate for flicker chifukwa cha mphamvu zotakataka.
Mtengo wa Noker Electricfyuluta yamphamvu yogwiraimatengera luso lapamwamba kwambiri la magawo atatu, okhala ndi mawonekedwe ang'onoang'ono, kachulukidwe kamphamvu kwambiri, magwiridwe antchito okhazikika komanso odalirika, omwe amayamikiridwa ndi makasitomala. Itha kungochita ulamuliro wa harmonic, kubweza mphamvu yogwira ntchito, komanso imatha kuchita ulamuliro wa harmonic + mphamvu yogwira ntchito. Malipiro, ma frequency a harmonic kuchokera ku 3 mpaka 50 ma harmonic, amatha kukulitsa kukhathamiritsa kwa gridi yanu.
