Grounding mafomu uye zvakakosha zvinodiwa zvepasi-voltage magetsi ekugovera masisitimu Kuti ushandire pamwe nemidziyo yekudzivirira mheni senge mudziyo wekudzivirira surge  mumasisitimu emagetsi akadzika-voltage kuburitsa mheni, kudzika mumasisitimu emagetsi epasi-voltage kunofanirwa kuzadzisa zvinotevera zvinodiwa: 1. Mafomu ekugadzirisa pasi pasi pasi anogona kugoverwa kuva marudzi matatu: TN, TT, uye IT. Pakati pavo, iyo TN system inogona kukamurwa kuva marudzi matatu: TN-C, TN-S uye TN-C-S. 2. Chimiro chepasi chepasi-voltage simba rekugovera simba rinofanira kugadziriswa maererano nezvinodiwa zvekuchengetedzwa kwemagetsi ekuchengetedzwa kwegadziriro. 3. Apo chidziviriro chekudzivirira uye chigadziro chekushanda chichigovera chigadziro chimwechete chekugadzirisa, zvinodiwa zvakakodzera zvekudzivirira kwekudzivirira pasi zvinotanga kusangana. 4. Akafumurwa conductive zvikamu zvemagetsi kuisirwa hazvizoshandiswe senhevedzano shanduko yekubatanidza kune inodzivirira pasi conductors (PE). 5. Iyo inodzivirira pasi conductor (PE) ichaita zvinotevera zvinodiwa: 1.Iyo inodzivirira pasi conductor (PE) ichava nekudzivirirwa kwakakodzera pakurwisana nemagetsi, makemikari kana electrochemical kukuvara, electrodynamic uye thermal effects, nezvimwewo. 2. Zvidziviriro zvemagetsi emagetsi uye zvigadziriso zvekushandura hazvifaniri kuiswa munharaunda yekudzivirira pasi conductor (PE), asi nzvimbo dzekubatanidza dzinogona kubviswa chete nemidziyo inobvumirwa. 3.Paunenge uchishandisa zvigadzirwa zvemagetsi zvekutarisa pasi, zvikamu zvakakosha zvakadai sekushanda sensors, coils, transformers ikozvino, nezvimwewo hazvifaniri kubatanidzwa mumutsara mumudziyo wekudzivirira pasi. 4. Kana mutyairi wemhangura akabatanidzwa kune aluminium conductor, chinhu chakakosha chekubatanidza chemhangura nealuminium chinofanira kushandiswa. 6. Iyo mhiri-chikamu nharaunda yeanodzivirira grounding conductor (PE) inofanirwa kusangana nemamiriro emagetsi otomatiki akagurwa mushure menguva pfupi yedunhu, uye inogona kumirisana nekushushikana kwemagetsi uye mhedzisiro yekupisa kunokonzerwa nekukanganisa kunotarisirwa ikozvino mukati mekucheka- nguva yekuvharwa kwemudziyo wekudzivirira. 7. Iyo yakaderera-yakachinjika nzvimbo yeyakagadzika inodzivirira pasi conductor (PE) ichaenderana nezviri muChinyorwa 7.4.5 chechiyero ichi. 8. Iyo inodzivirira pasi conductor (PE) inogona kunge ine imwe kana kupfuura yeanotevera conductor: 1.Conductors mu-multi-core cables 2.Isulated kana isina maconductor akagoverwa nevanorarama conductor 3.Bare kana insulated conductors for fixed installations 4.Metal tambo mabhachi uye concentric conductor simba tambo dzinosangana ane simba uye thermally kugadzikana magetsi kuenderera. 9. Zvikamu zvesimbi zvinotevera hazvifaniri kushandiswa sekudzivirira pasi conductors (PE): 1.Metal mvura pombi 2.Metal pombi dzine gasi, mvura, hupfu, nezvimwewo. 3.Flexible kana bendable metal conduit 4.Flexible simbi zvikamu 5. Rutsigiro rwonzi, tambo yetambo, simbi inodzivirira mukoto
