Dịka akụkụ bụ isi nke sistemụ nchekwa àmụ̀mà, nhọrọ mkpanaka àmụ̀mà kwesịrị imetụta nchekwa ụlọ ozugbo. Mkpebi ahụ kwesịrị ịhazi nkọwapụta teknụzụ, ihe ndị metụtara gburugburu ebe obibi, na nrubeisi iwu.
1. Ụdị Nhọrọ site na Ọrụ
Franklin Rods: Ọ dị mma maka ụlọ obibi nwere radius nchebe mita 30. Ọ chọrọ ihe owuwu ígwè galvanized na grid ntọala pụrụ iche.
Mkpanaka ESE (Early Streamer Emission): Gbasaa mkpuchi ruo mita 100 site na iji ihe mkpali eletrọniki, nke dị mma maka ebe dị mkpa dịka ebe data. Lelee asambodo CE/UL.
Mkpanaka redioaktivu (Amachibidoro): Amachibidoro iwu n'ime ụlọ ọhụrụ ndị China kwa GB 50057 kemgbe 2005 n'ihi ihe egwu radieshon.
02. Injinịa Pụrụ Iche Maka Gburugburu Ebe Obibi
Ngụkọta Ogologo: Tinye usoro ntụgharị okirikiri $ h = \sqrt{2rH – H^2}$ (h: ogologo mkpanaka, r: radius okirikiri, H: ogologo nhazi)
Nguzogide Njehie: Jiri ígwè anaghị agba nchara 316L (nguzogide nfesa nnu> awa 720) n'akụkụ osimiri; ngwakọta ọla kọpa-titanium (nkwụsị pH 2-12) maka mpaghara kemịkalụ
Njupụta Àmụ̀mà: N'ebe ndị na-arụ ọrụ nke ọma (karịa ụbọchị 90 nke oké ifufe kwa afọ), mụbaa elektrọd ndị na-ada ala site na 25%.
03. Nwụnye nke dabara na koodu
Usoro Nhazi: Nọgide na-enwe ike iguzogide ala <10Ω (<4Ω maka ụlọ ọrụ pụrụ iche), tinye sistemụ TN-S/TT n'ọrụ
Nhazi: Tinye njikọta thermite maka ọdụ ikuku/ndị na-eduzi ala nke karịrị 12cm
Nnyocha: Nnwale mgbochi mkpali site na mita CDM-10 pulse current; lelee njikọ ya na ihe onyonyo infrared
Ndụmọdụ Maka Mmezi: Jiri obere ohmmeters nyochaa iguzogide ala ugboro abụọ n'afọ, dochie mkpuchi ndị na-eduzi ala kwa afọ ise iji hụ na IEC 62305 na-agbaso usoro nchekwa ahụ n'oge niile.
