QTLD/F fa'ata'ita'iga vaega fa'atumu paipa electromagnetic mita tafe o se ituaiga o mea faigaluega fua e fa'aogaina le auala saosaoa-vaega e fa'aauau ai le fuaina o le vai i totonu o paipa (e pei o paipa fa'amama paipa ma paipa lapopo'a e aunoa ma ni fa'afefe). E mafai ona fua ma faʻaalia faʻamatalaga e pei o le tafe vave, saoasaoa o le tafe, ma le faʻaputuga o le tafe. E sili ona talafeagai mo manaʻoga o vai timu a le malo, vai leaga, lafoai o otaota ma paipa vai faʻafefe ma isi nofoaga e fua ai.
vaega: 1. E fetaui lelei mo le maualalo o le tafe o le suavai conductive 2. E mafai ona fua i lalo ile 10% le fa'atumuina ole paipa 3. Sa'o maualuga: 2.5% 4. Lagolago ituaiga eseese o galuega faatino faailoilo 5. Fuaina e lua 6. E talafeagai mo paipa liʻo, paipa sikuea ma isi.
