Mafomu oyika pansi ndi zofunikira zofunika pamagetsi otsika kwambiri ogawa magetsi Kuti mugwirizane ndi zida zotetezera monga zida zotetezera zopepuka mu makina otsetsereka owoneka bwino kuti zithetse mphezi, zomwe zimatsika muyeso wamagetsi otsika ziyenera kukwaniritsa zofunikira zotsatirazi: 1. Mawonekedwe apansi a dongosolo lotsika akhoza kugawidwa mu mitundu itatu: TN, TT, ndi IT. Pakati pawo, dongosolo TN akhoza kugawidwa mu mitundu itatu: TN-C, TN-S ndi TN-C-S. 2. Mawonekedwe apansi a magetsi otsika kwambiri a magetsi ayenera kutsimikiziridwa molingana ndi zofunikira zenizeni za chitetezo cha chitetezo cha magetsi cha dongosolo. 3. Pamene maziko otetezera ndi malo ogwirira ntchito akugawana ndi woyendetsa pansi womwewo, zofunikira zoyenera kwa woyendetsa pansi zotetezera ziyenera kukumana poyamba. 4. Zigawo zowonekera zoyika magetsi sizigwiritsidwa ntchito ngati zolumikizirana zachitetezo cha Earth conductors (PE). 5. Woyendetsa dziko lapansi (PE) adzakwaniritsa zofunikira izi: 1.The protective earth conductor (PE) adzakhala ndi chitetezo choyenera ku kuwonongeka kwa makina, kuwonongeka kwa mankhwala kapena electrochemical, electrodynamic ndi matenthedwe zotsatira, etc. 2. Zida zamagetsi zodzitchinjiriza ndi zida zosinthira sizingayikidwe mudera la protective earth conductor (PE), koma malo olumikizira omwe amatha kulumikizidwa ndi zida amaloledwa. 3.Pogwiritsa ntchito zida zowunikira magetsi kuti ziwonetsedwe pansi, zigawo zapadera monga masensa ogwirira ntchito, ma coils, otembenuza panopa, ndi zina zotero siziyenera kulumikizidwa mndandanda muzitsulo zotetezera pansi. 4. Pamene woyendetsa mkuwa akugwirizanitsidwa ndi woyendetsa aluminiyumu, chipangizo chapadera cholumikizira mkuwa ndi aluminiyumu chiyenera kugwiritsidwa ntchito. 6. Malo ozungulira gawo la kondakitala woteteza (PE) ayenera kukwaniritsa zofunikira kuti magetsi azimitsidwa pakadutsa kagawo kakang'ono, ndipo amatha kupirira kupsinjika kwamakina ndi zotsatira za kutentha zomwe zimachitika chifukwa cha vuto lomwe likuyembekezeka mkati mwa odulidwa- nthawi yopuma ya chipangizo choteteza. 7. Malo ocheperako a gawo laling'ono lachitetezo cha nthaka (PE) azitsatira zomwe zili mu Article 7.4.5 za muyezowu. 8. Woteteza dziko lapansi (PE) akhoza kukhala ndi kondakitala mmodzi kapena angapo awa: 1.Makonda mu zingwe zamitundu yambiri 2.Makondakitala opangidwa ndi insulated kapena opanda kanthu omwe amagawana ndi ma conductor amoyo 3.Bare kapena insulated conductors kwa makhazikitsidwe okhazikika 4.Zingwe zazitsulo zazitsulo ndi zingwe zamagetsi za concentric conductor zomwe zimakwaniritsa kupitilira kwamagetsi kwamphamvu komanso kokhazikika 9. Zigawo zotsatirazi zazitsulo sizidzagwiritsidwa ntchito ngati zotetezera nthaka (PE): 1.Chitoliro chamadzi chazitsulo 2.Metal mapaipi okhala ndi mpweya, madzi, ufa, etc. 3.Flexible kapena bendable zitsulo ngalande 4.Zigawo zachitsulo zosinthika 5. Waya wothandizira, thireyi ya chingwe, ngalande yoteteza zitsulo
