Harmonics e hlaha khafetsa bophelong ba rona ba letsatsi le letsatsi.The khafetsa ho fumana ho ba teng phahameng ea harmonics hangata lipetlele, liunivesithing, litsi tsa 'muso, litsi tsa mabenkele, laboratories, liindasteri boima, seea-le-moea, TV, kgaso, indasteri ya dijo, hotel le casino, indasteri e itirisang haholo, ho hloekisa metsi. lisebelisoa tse tloaelehileng tse hlahisang li-harmonic tse kenyelletsang: ho fetola lisebelisoa tsa motlakase, li-welders, li-Ups, converter ea khale ea motlakase e nang le theknoloji ea thyristor power converter, li-motor drive, li-converter tse nang le li-rectifier tse laoloang, molaoli oa DC bakeng sa li-drive tsa DC, li-ovine tsa Induction.
Litlamorao tse ka sehloohong tsa li-harmonics ke tse latelang:
1.Ho futhumala ho feteletseng le ho sisinyeha ka botsofali pele ho nako ea likarolo tsohle, ka litlamorao tsa nako e khuts'oane le e mahareng tebello ea bophelo.
2.Faults ka thepa ea motlakase ea motlakase.
3.Tšenyo ea likarolo tsa boto ea potoloho e hatisitsoeng.
4.Motlakase oa motlakase o feteletseng.
5.Pele ho tsofala capacitor le tšenyo ka lebaka la resonance.
6.Ho fokotsa matla a matla.
7.Overload ea terata e sa nke lehlakore.
8.Tsusumetso ea motlakase.
Liphoso tsa 9.Measurement metres ea matla.
10.MCCB le contactor tšitiso phoso.
11. Ho khoptjoa ho sa nepahalang ha switjha.
Li-filters tse sebetsang tsa harmonicke lisebelisoa tsa boleng ba matla tse fanang ka matla a motlakase a laoloang a nang le amplitude e tšoanang le ea harmonic hona joale, e kenngoang khahlanong le li-harmonics tsa marang-rang.Sena se tla felisa matla a harmonic tsamaisong ea motlakase.Ka lebaka leo, hona joale e fanoang ke mohloli oa matla e tla lula e le sinusoidal ha li-harmonics li tla hlakola 'me ho senyeha ha harmonic ho tla fokotsoa ho ea bohlokoa haholo.
Lisefe tse sebetsange ka kenngoa kae kapa kae marang-rang mme e fana ka likarolo tse ngata:
1.Felisa maqhubu 'ohle a harmonic ho fihlela ho taelo ea 50 ho tloha meroalo e sa tloaelehang.
2.Compensate matla a sebetsang le ho lokisa ntlha ea matla.
3.Compensate for flicker e bakiloeng ke matla a sebetsang.
Noker Electricsetlhoa sa matla se sebetsange amohela theknoloji e tsoetseng pele ea maemo a mararo, e nang le litšoaneleho tsa boholo bo bonyenyane, matla a phahameng a matla, ts'ebetso e tsitsitseng le e tšepahalang, e ratoang ke bareki. E ka etsa puso ea harmonic, puseletso ea matla a sebetsang, hape e ka etsa puso ea harmonic + matla a sebetsang. puseletso, maqhubu a harmonic ho tloha ho 3 ho isa ho 50 harmonic, a ka eketsa ntlafatso ea boleng ba gridi ea hau.
