Mheni inodzivirira nzvimbo pfungwa
Iyo mheni yekudzivirira zone pfungwa inobvumira kuronga, kuita uye kuongorora matanho ekudzivirira. 
Midziyo yose inoenderana, kuiswa, uye masisitimu anofanirwa kuchengetedzwa zvakavimbika kusvika padanho rine hupfumi. Kusvikira pane izvi, chivakwa chakakamurwa kuita matunhu ane mikana yakasiyana yenjodzi. Zvichienderana nenzvimbo idzi, matanho anodiwa ekudzivirira anogona kusarudzwa, kunyanya, mheni uye ekuwedzera ekuchengetedza michina uye zvikamu.
EMC-based (EMC = electromagnetic kuenderana) mheni yekudzivirira nzvimbo yenzvimbo inosanganisira yekuvhenekerwa kwekuvhenekera kwekunze (mhepo-inogumisa system, pasi conductor, earthing), equipotential bonding, spatial shielding uye surge kudzivirira kwesimba rekupa uye ruzivo rwetekinoroji system. Nzvimbo dzekudzivirira mheni dzinotsanangurwa pazasi.
Mheni yekudzivirira nzvimbo nenzvimbo dzakazara dzekudzivirira
Midziyo yekudzivirira inowedzeredzwa semheni dzemazuva ano vanosunga, vanosungwa, uye vakasungwa vakasungwa zvinoenderana nezvinodiwa panzvimbo yavo yekumisikidza. Mheni yazvino uye yakasanganiswa inosunga iyo yakaiswa panguva yekuchinja kubva kuLPZ 0A kusvika 1 / LPZ 0A kusvika 2 kuzadzisa zvakanyanya kuomesesa zvinodiwa maererano nechaji chinzvimbo. Vaya vanosunga vanofanirwa kuve vanokwanisa kuburitsa zvishoma magetsi emagetsi e10 / 350's waveform kanoverengeka pasina kuparadza, nekudaro ichidzivirira jekiseni remhepo inoparadza isina kukwana mune yekuisa magetsi kwechivako.
Vakawedzera vanosungwa vanoisirwa panguva yekuchinja kubva kuLPZ 0B kuenda ku1 uye kuzasi kwerwizi rwemheni rwuri musungwa panguva yekuchinja kubva kuLPZ 1 kusvika 2 uye kumusoro. Basa ravo kudzikisira masarasara ematanho ekudzivirira ekumusoro uye kudzikamisa iwo mafuru anokonzerwa mukuisirwa kana kugadzirwa mukuisirwa.
Iyo inotsanangurwa mheni uye yekuwedzera matanho ekudzivirira pamiganhu yenzvimbo dzekudzivirira mheni dzinofanirwa kutorwa zvese kune magetsi uye neruzivo matekinoroji masisitimu. Iyo inoenderana kuitiswa kweakatsanangurwa matanho anochengetedza kusingaperi kuwanikwa kwezvivakwa zvazvino.
Tsananguro yenzvimbo dzekudzivirira mheni
LEMP dziviriro yezvivakwa nemagetsi uye emagetsi masisitimu zvinoenderana neIEC 62305-4
LPZ0A Nzvimbo uko kutyisidzira kuri nekuda kwechiedza chemheni chaicho uye izere nemheni magetsi magetsi. Masisitimu emukati anogona kuiswa pasi pemheni izere yemagetsi.
LPZ0B Nzvimbo yakachengetedzwa kubva kune mheni yakananga inopenya asi panotyisidzira ndiyo izere mheni yemagetsi magetsi. Iyo yemukati masisitimu inogona kuiswa pasi peimwe mheni kuwedzera mafashama.
LPZ1 Nzvimbo iyo yazvino kufefetera inogumira nekugovana kwazvino uye nemaSPD pamuganho. Spatial kudzivirirwa kunogona kudzikisira mheni yemagetsi magetsi.
LPZ2 Nzvimbo iyo yazvino kuitika inogona kuve yakaganhurirwa nekugovana kwazvino uye nemamwe maPSD pamuganho. Kuwedzera kwenzvimbo kudzivirirwa kunogona kushandiswa kuenderera mberi nekudzima mheni yemagetsi magetsi.
