Dịka akụkụ bụ isi nke sistemụ nchekwa àmụ̀mà, nhọrọ mkpanaka àmụ̀mà kwesịrị imetụta nchekwa ụlọ ozugbo. Mkpebi a 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.
