Ikhono le-SPD lokukhawulela ama-overvoltages kunethiwekhi yokusabalalisa ngokuphambukisa amandla amanje akhuphukayo lincike ezingxenyeni zokuvikela ukukhuphuka, ukwakheka komshini kwe-SPD, kanye nokuxhumeka kunethiwekhi yokusabalalisa. Ama-SPD aklanyelwe ukukhawulela ama-overvoltage esikhashana futhi aguqule ama-inrush currents, noma kokubili. Iqukethe okungenani ingxenye eyodwa engaqondile. Kalula nje, ama-SPD aklanyelwe ukukhawulela ukugcwala ngokweqile kwesikhashana ukuvimbela ukulimala kwemishini.

Ukubaluleka kwe-SPD akukwazi ukweqiwa, ikakhulukazi kulesi sikhathi samanje lapho izinto zikagesi ezibucayi zitholakala yonke indawo ezindaweni zokuhlala nezohwebo. Njengoba ukuthembela emishinini kagesi namathuluzi kwanda, ingozi yokulimala okuvela ekuqhumeni kwamandla kanye nokweqile kwesikhashana iba nkulu kakhulu. Ama-SPD ayindlela yokuqala yokuzivikela ngokumelene nalolu hlobo lokuphazanyiswa kukagesi, ukuqinisekisa ukuthi imishini ebalulekile ivikelekile futhi ivimbela ukuphumula ngenxa yokulimala.

Imisebenzi ye-SPD inhlobonhlobo. Ayikhawuleli nje kuphela ama-overvoltages esikhashana ngokuphambukisa ama-surge currents, kodwa futhi iqinisekisa ukuthi inethiwekhi yokusabalalisa amandla ihlala izinzile futhi ithembekile. Ngokuphambukisa ama-surge currents, ama-SPD asiza ukuvimbela izingcindezi ezingaholela ekulimaleni kwe-insulation, ukulimala kwemishini kanye nezingozi zokuphepha ezingaba khona. Ukwengeza, bahlinzeka ngezinga lokuvikela lamathuluzi e-elekthronikhi azwelayo angase abe lula ekushintshashintsheni okuncane kwamandla kagesi.

Ukwakheka komshini kwe-SPD nakho kunomthelela ekusebenzeni kwayo, njengoba kufanele ikwazi ukumelana namandla okwanda ngaphandle kokwehluleka. Ukwengeza, ukuxhuma kunethiwekhi yokusabalalisa amandla nakho kubalulekile, njengoba ukufakwa okufanele kanye nokubekwa phansi kubalulekile ekusebenzeni kahle kwe-SPD.

Ama-SPD atholakala ngezinhlobo ezihlukahlukene nokulungiselelwa, okuhlanganisa uhlobo 1, uhlobo 2 kanye namadivayisi ohlobo 3, ngalinye lifanele izinhlelo zokusebenza ezahlukene nezindawo zokufakwa. Kunconywa ukuthi uthintane nochwepheshe oqeqeshiwe ukuze uqinisekise ukuthi i-SPD ikhethwe kahle futhi ifakwe ukuze inikeze izinga elidingekayo lokuvikela.

Kafushane, amadivayisi okuvikela ukuhlikihla (ama-SPD) adlala indima ebalulekile ekuvikeleni amanethiwekhi okusabalalisa amandla kanye nezinto zokusebenza ze-elekthronikhi ezibucayi emiphumeleni elimazayo yokugcwala ngokweqile kanye nokwanda kwamandla. Ikhono labo lokukhawulela ukudlula kwamandla esikhashana kanye nokuphambukisa ama-inrush currents kubalulekile ekugcineni ukuqina nokuthembeka kwezinhlelo zikagesi. Njengoba okokusebenza kwe-elekthronikhi kuqhubeka kwanda, ukubaluleka kwama-SPD ekuvikeleni ekukhuphukeni kwamandla kanye nokweqisa kwesikhashana akukwazi ukubukelwa phansi. Ukukhethwa okufanele, ukufakwa nokugcinwa kwama-SPD kubalulekile ekuqinisekiseni ukuvikelwa okuqhubekayo kwemishini ebalulekile kanye nokusebenza okungaphazamiseki kwezinhlelo zikagesi.
