Incazelo emfushane:

Isivikelo sombani siyisivikelo se-overvoltage, ikakhulukazi sokuvikela uhlelo lwamandla kagesi, izinhlelo zikagesi zesitimela, izinhlelo zokuxhumana ezinhlobonhlobo zemishini kagesi (i-transformer,
I-switch, i-capacitor, i-trapper, ama-transformer, ama-generator, ama-motor, izintambo zikagesi) ezivela emoyeni ongaphezu kwamandla kagesi, i-overvoltage kanye ne-transient over-voltage umonakalo onjalo, uyisisekelo sokuhlanganiswa kokufakwa kwesistimu yamandla.
Isivimbeli sokukhuphuka kwe-oxide yensimbi yezingxenye eziyinhloko (ama-resistor) esinokwakheka okuthuthukisiwe okusekelwe ku-zinc oxide, sinezici ezinhle kakhulu ezingezona eziqondile (VA), okungukuthi ku-voltage evamile yokusebenza, ugesi ngesigaba se-microampere kuphela, lapho sibhekene ne-voltage, ugesi ngesikhashana esifinyelela izinkulungwane zama-ampere, okwenza ku-lightning arrester on-state voltage, ukukhishwa kwamandla, ngaleyo ndlela kukhawulele ngempumelelo
ugesi omningi kakhulu ekulimaleni komshini wokudlulisa amandla kanye nokuguqulwa kwawo.
Isivikelo sokukhuphuka kwe-silicon carbide yendabuko sibangelwa ukubambezeleka kokukhishwa kwamagagasi amakhulu okubangelwa yi-voltage yokukhishwa kwamagagasi amakhulu iphezulu, ukusabalala kokukhishwa kwamagagasi okusebenza ku-voltage yokukhishwa kwamagagasi okusebenza
okuphezulu. Isivikelo sokukhuphuka kwe-zinc oxide esinokusabela okuhle kwamagagasi kagesi, ngaphandle kokulibala, ukuncipha kokusebenza okusele, ukusabalala kokukhipha njll. Igagasi elinamandla, umkhawulo wokuvikela amagagasi uyathuthuka
kakhulu, kodwa futhi nasekuhlanganiseni kokufakwa kokushisa, kungaba amagagasi amakhulu, umbani, umkhawulo wokuvikela wamagagasi okusebenza cishe ngokulinganayo, ukuze kunikezwe isivikelo esingcono kakhulu semishini yamandla kagesi.
Isivikelo sombani sensimbi esihlanganisiwe esimbozwe nge-oxide, sisebenzisa ukubumba okuhlanganisiwe komjovo, ubuchwepheshe bokuvala obubili, ukusebenza kahle kokuvala, ukusebenza kahle kokuvikela ukuqhuma, futhi singanciphisa ukungcola
ukuhlanza okungenawo ukumelana nenkungu, izinwele ezimanzi, ukumelana nokuguguleka kukagesi, ukumelana nokuguga, ivolumu encane, isisindo esincane, ukufakwa nokugcinwa okulula. I-Porcelain iyisethi yesivikelo sombani se-
ukuthuthukiswa kwemikhiqizo.
