Mphamvu yamagetsi ikagwiritsidwa ntchito, imatha kukhala yolumikizidwa molakwika kapena kufupikitsidwa.Kuphatikiza apo, mphamvu yokhayo imatha kusokonekera ndikupangitsa kuti voliyumu yotulutsa ikhale yachilendo.Choncho, pakupanga ndi kupanga magetsi, ndondomeko za chitetezo ndizofunikira kwambiri.Pali mbali ziwiri za chitetezo cha magetsi, chimodzi ndi kuteteza zipangizo zina kuti ziwotchedwe, ndipo zina ndizodziteteza kuti zisawonongeke.
Kutetezedwa kwa magetsi kunja kumakhala makamaka kupitirira-voltage ndi under-voltage chitetezo, kutanthauza kuti pamene mphamvu yotulutsa mphamvu yamagetsi ikukwera kwambiri kapena yotsika kwambiri kuti ikhale yachilendo, magetsi amasiya kugwira ntchito.Izi ndizofunikira kwambiri pamakina onse, chifukwa zida zambiri zamtengo wapatali zimakhala zosalimba, ndipo ndizosavuta kuziwotcha chifukwa champhamvu kwambiri.
Pofuna kupewa izi, ndikofunikira kuyang'anira voteji iliyonse yamagetsi amagetsi.Njira ya wopanga mphamvu ndikuyesa voteji yotulutsa kudzera mugawo lachitsanzo, ndipo chizindikiro chojambulidwa chimalumikizidwa ndi gawo lowongolera kudzera mu comparator.Mphamvu yotulutsa ikakhala yachilendo, chizindikiro cha sampuli chidzawonetsedwa nthawi yomweyo, ndipo gawo lowongolera lidzadziwitsidwa kuti litseke.Izi zitha kuteteza bwino mbali zolumikizira kumbuyo.Kaya magetsi ali ndi chitetezo chothamanga kwambiri ndikofunikira kwambiri pamakina onse.Pofuna kupewa kupsa mtima chifukwa cha kuchuluka kwa magetsi, magetsi amakhala ndi fusesi.
