Cov tshuab hluav taws xob tuaj yeem muab faib ua DC generators thiab AC generators. Txij li thaum lub tshuab hluav taws xob AC yog qhov zoo tshaj rau DC lub tshuab hluav taws xob hauv ntau yam, DC generators tau raug tshem tawm. Tam sim no, txhua lub tsheb siv AC generators, thiab AC generators raug faib raws li ntau txoj kev. Muab faib ua pawg hauv qab no:
1. Raws li tag nrho cov qauv ntawm cov pob caus, nws muab faib ua tsib pawg
2. Raws li cov qauv ntawm lub rectifier muab faib ua plaub pawg
3. Raws li ob qhov kev faib tawm ntawm daim teb winding grounding daim ntawv
