Faʻavae i luga o le poto masani o le poto masani o le mana, pe a tatou filifilifaamama harmonic malosi, e lua fua fa'atatau e masani ona fa'aogaina e fa'atatau ai le gafatia o le fa'amalo fa'atasi.
1.Centralized pulega: Fa'atatau le gafatia fa'atulagaina o pulega fa'atasi e fa'atatau i le fa'avasegaina o alamanuia ma le gafatia o le transformer.
S ---- Transformer fua fa'atatau, U---- Fa'atulagaina voltage i le itu lona lua o le U-transformer
Ih---- Harmonic current, THDi----Aofa'i fua fa'aletonu i le taimi nei, fa'atasi ai ma le tele o tau fa'atatau e fa'atatau i luga o pisinisi eseese po'o uta.
K---- Transformer fua faatatau uta
| Ituaiga alamanuia | Fa'asologa masani fa'aletonu% |
| Alalaupapa, Tunnels, nofoaafi televave, Malaeva'alele | 15% |
| Fesootaiga, fale faapisinisi, Faletupe | 20% |
| Alamanuia faafomai | 25% |
| Gaosi taavale, gaosiga o vaa | 30% |
| Chemical\Petroleum | 35% |
| Alamanuia metallurgical | 40% |
2. I luga o le nofoaga pulega: Fa'atatau le gafatia fa'atulagaina o pulega fa'atasi e fa'avae i luga o 'au'aunaga uta eseese.
Ih---- Harmonic current, THDi----Aofa'i fua fa'aletonu o lo'o iai nei, fa'atasi ai ma le tele o tau fa'atatau e fa'atatau ile eseese o alamanuia po'o uta.
K--- Transformer fua faatatau uta
| Tulaga uta | Mea masani fa'akomepiuta% | Tulaga uta | Mea masani fa'akomepiuta% |
| Inverter | 30---50 | Fa'asalaina fa'avevela fa'avevela fa'avevela | 30---35 |
| Lifi | 15---30 | E ono fa'asa'o fa'amalosi | 28---38 |
| moli LED | 15---20 | Fa'asa'o fa'asa'o e sefululua | 10---12 |
| Lamepa laveai malosi | 15---30 | masini uelo eletise | 25---58 |
| palasi faaeletonika | 15---18 | Ea malulu fealua'i | 6----34 |
| Suia le auala sapalai eletise | 20---30 | UPS | 10---25 |
Manatua: O fa'atusatusaga o lo'o i luga ua na'o fua fa'atatau mo fa'amatalaga.
Pe a tatou filifilistatic var generator, lua fua fa'atatau e masani ona fa'aogaina e fa'atatau le gafatia o le taui malosi fa'afoliga.
1. Fa'atatau e fa'atatau i le gafatia o le transformer:
20% i le 40% o le transformer gafatia o loʻo faʻaaogaina e faʻapipiʻi ai le malosi o le taui o le malosi, ma se filifiliga lautele o le 30%.
Q=30%*S
Q ---- Reactive mana taui gafatia, S---- Transformer gafatia
Mo se faʻataʻitaʻiga, o le 1000kVA transformer o loʻo faʻapipiʻiina i le 300kvar reactive power compensation.
2.Calculate faʻavae i luga o le malosiaga ma le malosi malosi o meafaigaluega:
Afai o loʻo i ai faʻamatalaga auiliili o uta, e pei o le maualuga o le malosi malosi P, le malosiaga COSO aʻo leʻi totogia, ma le faʻaogaina o le malosiaga COSO pe a maeʻa le taui, o le gafatia moni e manaʻomia mo le faiga e mafai ona fuafua saʻo:
Q----Reactive mana taui gafatia, P----Maximum malosi malosi
K---- avefeau ave fa'atatau (e masani ona ave e pei ole 0.7--0.8)
Manatua: O fa'atatauga o lo'o i luga e mo na'o fa'amatalaga.
O lo'o naunau le Noker Electric i le tu'uina atu i tagata fa'atau le fa'atonuga o le mana fa'afoliga fa'atasi ma tali fa'amalieina, so'o se fesili ile filifiliga o oloa, e te lagona le saoloto e fa'afeso'ota'i i matou.
