Achoteteza magetsi imateteza zida zamagetsi poyang'anira magetsi omwe akubwera ndikuchotsa mphamvu zokha magetsi akatuluka pamalo otetezeka, okonzedweratu (okwera kwambiri kapena otsika kwambiri)Mphamvu yamagetsi ikakhazikika ndikubwerera pamlingo wabwinobwino, chipangizocho chimabwezeretsanso mphamvu yamagetsi. Ntchito zake zazikulu zimaphatikizapo kuteteza mphamvu yamagetsi, chitetezo cha under-voltage (chitetezo cha brownout), komanso kupereka nthawi yochepetsera mphamvu pambuyo pobwezeretsa mphamvu yamagetsi pazida zofewa monga ma compressor.

Ntchito Zofunika Kwambiri za Woteteza Voltage

• Chitetezo cha magetsi ochulukirapo:
  Zimateteza ku kukwera kwadzidzidzi kwa magetsi, komwe kumadziwika kuti ma surges kapena spikes, komwe kungawononge zigawo zamagetsi zomwe zimakhudzidwa.
• Chitetezo cha pansi pa magetsi:
  Zimateteza ku brownouts (voteji yotsika) mwa kudula mphamvu kuti zisawonongeke zomwe zingachitike ngati zipangizo zikuyenda ndi voteji yosakwanira.
• Chowerengera Nthawi Chochedwa:
  Chinthu chofunika kwambiri pa zipangizo monga mafiriji kapena ma air conditioner omwe amafunika kudikira nthawi yayitali magetsi atachepa mphamvu isanabwezeretsedwe. Izi zimathandiza kuti mpweya womwe uli mu compressor ukhazikike, zomwe zimathandiza kuti compressor isawonongeke.
• Kulumikizanso Kokha:
  Mphamvu yamagetsi ikabwerera pamalo otetezeka komanso okhazikika, chotetezera chimabwezeretsa mphamvu yamagetsi ku zida zolumikizidwa.
• Kuwunika ndi Kulamulira:
  Imayang'anira nthawi zonse kuchuluka kwa magetsi m'makina amagetsi ndipo imachitapo kanthu ikazindikira vuto lililonse lomwe lingayambitse kuwonongeka kwa zida.

Chifukwa Chake Zoteteza Ma Voltage Ndi Zofunika

• Kutalika kwa Zida:
  Zimaletsa kuwonongeka msanga kwa zipangizo zamagetsi ndi zipangizo zina.
• Chitetezo:
  Zimathandiza kupewa kutentha kwambiri, ma short circuit, ndi zina zomwe zingawononge magetsi.
• Yotsika Mtengo:
  M'malo mosintha zida zowonongeka, choteteza magetsi chimapereka njira yotsika mtengo yopewera kukonza kapena kusintha zinthu zodula.
