    Isikhokelo soKhetho lweNkqubo yoNikezelo lwaMandla e-SPD

    Ukufakelwa kwe-SPD kwindawo nganye yokukhusela umbane, ngokwemigangatho yembonakalo yombane ene-voltage ephantsi, kwahlula izixhobo zombane ngokwemigangatho ye-overvoltage, inqanaba lazo le-insulation standing impulse voltage linokumisela ukhetho lwe-SPD. Ngokwemigangatho yembonakalo yombane ene-voltage ephantsi, kwahlula izixhobo zombane ngokwemigangatho ye-overvoltage njengenqanaba lesiginali, inqanaba lokulayisha, inqanaba lokusasazwa kunye nenqanaba lolawulo, inqanaba lombane. Inqanaba lazo le-insulation standing impulse voltage zezi: 1500V, 2500V, 4000V, 6000V. Ngokwendawo yokufakela izixhobo ezikhuselweyo, kukho indawo eyahlukileyo kunye nomsinga wombane owahlukileyo weendawo ezahlukeneyo zokukhusela umbane, ukumisela indawo yokufakela ye-SPD yokubonelela ngombane kunye nomthamo wokuqhekeka.
    Umgama wokufakelwa phakathi kwenqanaba ngalinye le-SPD akufuneki ube ngaphezulu kwe-10m, umgama phakathi kwe-SPD kunye nezixhobo ezikhuselweyo kufuneka ube mfutshane kangangoko, ungabi ngaphezu kwe-10m. Ukuba ngenxa yokunciphisa indawo yokufakelwa, akunakuqinisekiswa umgama wokufakelwa, kufuneka ufake icandelo lokudibanisa phakathi kwenqanaba ngalinye le-SPD, wenze iklasi elandelayo ye-SPD ikhuselwe yiklasi yangaphambili ye-SPD. Kwinkqubo yombane ophantsi, ukudibanisa i-inductor kunokufezekisa injongo yokudibanisa.
    I-SPD yomgaqo wokukhetha iinkcukacha zenkqubo yokubonelela ngombane
    I-voltage yokusebenza eqhubekayo ephezulu: inkulu kunezixhobo ezikhuselweyo, i-voltage yokusebenza eqhubekayo ephezulu kakhulu yenkqubo.
    Inkqubo ye-TT: Uc≥1.55Uo (Uo yinkqubo ye-voltage ephantsi ukuya kwi-voltage yomgca ongenanto)
    Inkqubo ye-TN: Uc≥1.15Uo
    Inkqubo ye-IT: Uc≥1.15Uo(Uo yinkqubo ye-voltage ephantsi ukuya kwi-voltage yomgca)
    Inqanaba loKhuseleko lweVoltage: ngaphantsi kwe-insulation ukumelana ne-voltage yempembelelo yezixhobo ezikhuselweyo
    Umsinga wokukhupha olinganiselweyo: umiselwe ngokwemeko yombane kwindawo efakiweyo kunye nendawo yokukhusela umbane.
