Umbambeli uqhagamshelwe phakathi kwentambo kunye nomhlaba, ngokuqhelekileyo ngokuhambelana nezixhobo ezikhuselweyo. Umbambisi unokukhusela ngokufanelekileyo izixhobo zonxibelelwano. Nje ukuba kubekho amandla ombane angaqhelekanga, umbambeli uya kwenza kwaye adlale indima yokukhusela. Xa ikhebula lonxibelelwano okanye izixhobo zisebenza phantsi kombane osebenzayo oqhelekileyo, umbambeli akayi kusebenza, kwaye uthathwa njengesiphaluka esivulekileyo emhlabeni. Nje ukuba kubekho amandla ombane aphezulu kwaye ukugqunyelelwa kwezixhobo ezikhuselweyo kusengozini, umbambeli uya kuthatha inyathelo ngoko nangoko ukukhokela i-high-voltage surge yangoku emhlabeni, ngaloo ndlela enciphisa i-voltage amplitude kunye nokukhusela ukugqunywa kweentambo zonxibelelwano kunye nezixhobo. Xa i-overvoltage inyamalala, umbambisi ubuyela ngokukhawuleza kwisimo sawo sokuqala, ukwenzela ukuba umgca wonxibelelwano usebenze ngokuqhelekileyo.
Ngoko ke, umsebenzi oyintloko wokubanjwa kukunqumla i-wave wave ehlaselayo kunye nokunciphisa ixabiso le-overvoltage yezixhobo ezikhuselweyo ngokusebenza kwe-gap yokukhupha i-parallel okanye i-resistor nonlinear, ngaloo ndlela ikhusela umgca wonxibelelwano kunye nezixhobo. Izithinteli zombane zingasetyenziselwa ukukhusela kuphela kumbane ophezulu owenziwe ngumbane, kodwa nokukhusela ekusebenziseni amandla aphezulu.
Indima yombambi kukukhusela izixhobo ezahlukeneyo zombane kwisixokelelwano samandla ekonakalisweni kukugqithiswa kombane, ukugqithiswa kombane osebenzayo, kunye nokugqithiswa kwamandla okudlula okwexeshana. Iindidi eziphambili zokubamba i-gap yokukhusela, i-valve arrester kunye ne-zinc oxide arrester. I-gap yokukhusela isetyenziselwa ukukhawulela i-atmospheric overvoltage, kwaye isetyenziselwa ukukhuselwa kwecandelo lomgca ongenayo wenkqubo yokusabalalisa amandla, imigca kunye nezitishi. I-valve type arrester kunye ne-zinc oxide arrester isetyenziselwa ukukhuselwa kweendawo ezincinci kunye nezityalo zamandla. Kwiinkqubo ze-500KV nangaphantsi, zisetyenziswa ikakhulu ukunciphisa ukugqithiswa kwe-atmospheric. Ukhuseleko logcino.
