General ruzivo uye zvakakosha zvemheni kudzivirira grounding cheki 1. Tarisa matanho ekuvhiya kudzivirira grounding Edza kumira kwepasi kwesimbi dzemheni, zvivakwa zvepamusoro-soro uye zvimwe zvivakwa kuti uone kuti mheni inogona kuunzwa muvhu zvakanaka. Mheni kudzivirira grounding bvunzo nzira: 1. Kutanga tsvaga pasi inotungamira kana equipotential yekubatanidza bhokisi remheni kudzivirira grounding network. 2, ine grounding resistance tester kuyera kupikisa kwepasi (kune maviri bvunzo murwi 0.4M yekuisa ivhu, chinhambwe kubva pabvunzo point 20 metres, 40 metres, saka bvunzo inotenderera yakatenderedza 42 metres kuve nevhu) 3. Iyo idiki iyo yepasi yekupikisa kukosha, zviri nani. Iyo chaiyo yakakosha kukosha inofanira kutsanangurwa maererano nezvinodiwa zvekugadzira kana dhizaini ine zvinodiwa. 2. Tarisa uye chengetedza zvinhu uye zvidziviriro panguva yekushanda kwechidziviriro chekudzivirira grounding device Kana mudziyo wekudzivirira mheni uri kushanda, zvinodikanwa kusimbisa kuongorora kuti uone uye ubate zvisizvo uye kukanganisa munguva yekudzivirira iyo mheni yekudzivirira mudziyo kubva pakusashanda kana kuita kwechiedza chekudzivirira mheni. Zvinhu zvekuongorora zvakananga ndezvizvi: (1) Iyo mheni inotungamira chikamu chechishandiso chekudzivirira mheni, mutsara wekudzika pasi uye muviri wepasi wakanyatsobatanidzwa. (2) Kupikisa kwepasi kunofanirwa kuongororwa nguva dzose panguva yekushanda, uye kupikisa kwepasi kunofanira kusangana nezvinodiwa. (3) Zvibatiso zvemheni zvinofanira kugara zvichiitwa bvunzo dzekudzivirira. (4) Tsvimbo yemheni, conductor yemheni uye waya yayo yekumisa haifanirwe kunge isina kukuvara kwemuchina uye ngura chiitiko. (5) Sleeve yekudzivirira mheni inofanira kunge yakazara, pamusoro pacho panofanira kunge pasina kuputika, pasina kusvibiswa kwakakomba uye chiitiko chinopenya. (6) Nguva dzose nyora nguva dzekufamba kwemusungwa sezvinoratidzwa nerekodha yekubudiswa. (7) Chikamu chepasi chinofanira kunge chakanyatsodzika. Uye zvakare, isati yasvika mwaka wekutinhira kwegore negore, kuongororwa kwakadzama, kugadzirisa, uye bvunzo dzekudzivirira dzemagetsi dzinofanira kuitwa.
