Ukukhuselwa kwe-Surge kwiimveliso ze-elektroniki Kuqikelelwa ukuba i-75% yokungaphumeleli kwiimveliso ze-elektroniki zibangelwa ukuhamba kwexesha kunye nokunyuka. I-voltage transients kunye ne-surges zikho kuyo yonke indawo. Iigridi zamandla, ukubetha kombane, ukuqhushumba, kunye nabantu abahamba kwiikhaphethi baya kuvelisa amashumi amawaka eevolthi zombane owenziwe ngombane. Aba ngababulali abangabonakaliyo beemveliso ze-elektroniki. Ke ngoko, ukuze kuphuculwe ukuthembeka kweemveliso ze-elektroniki kunye nokhuseleko lomzimba womntu, kuyafuneka ukuba kuthathwe amanyathelo okhuseleko ngokuchasene nokuhamba kombane kunye nokunyuka. Kukho izizathu ezininzi zotyando. I-surge yi-spike enezinga eliphezulu lokunyuka kunye nexesha elifutshane. Ukugqithiswa kwegrid yamandla, ukucinywa kokutshintsha, umthombo obuyela umva, umbane ongatshintshiyo, ingxolo yemoto/yamandla, njl. Umkhuseli wokuqhafaza ubonelela ngendlela elula, eyongayo kwaye ethembekileyo yokukhusela ukukhuselwa kwamandla ombane wezixhobo zombane. Njengoko sonke sisazi, iimveliso ze-elektroniki zihlala zidibana nokudlula kwamandla ombane kunye nokunyuka okungalindelekanga ngexesha lokusetyenziswa, okukhokelela kumonakalo kwiimveliso zombane. Umonakalo ubangelwa izixhobo ze-semiconductor kwiimveliso ze-elektroniki (kubandakanywa i-diodes, i-transistors, i-thyristors kunye neesekethe ezidibeneyo, njl.) Itshiswa okanye idilizwe. Indlela yokuqala yokukhusela kukusebenzisa indibaniselwano yamandla ombane amaninzi adlulayo kunye nezixhobo zokhuselo lokunyuka koomatshini ababalulekileyo kunye neendleko ezipheleleyo kunye neenkqubo zokwenza isekethe yokhuseleko lwamanqanaba amaninzi. Indlela yesibini yokukhusela Kukuthoba umatshini wonke kunye nenkqubo. Umhlaba (isiphelo esiqhelekileyo) somatshini wonke kunye nenkqubo kufuneka ihlulwe emhlabeni. Umatshini wonke kunye nenkqubo ephantsi nganye kwinkqubo kufuneka ibe nesiphelo esifanayo esizimeleyo. Xa uhambisa idatha okanye izibonakaliso, umhlaba kufuneka usetyenziswe njengenqanaba lereferensi, kwaye ucingo lomhlaba (umphezulu) kufuneka lukwazi ukuhamba umsinga omkhulu, njengamakhulu amaninzi ama-amperes. Indlela yesithathu yokukhusela kukusebenzisa i-voltage edlulayo kunye nezixhobo ezikhuselayo kumatshini wonke kunye neendawo eziphambili zenkqubo (ezinje ngokuba ngabahloli bekhompyuter, njl.njl.), ukuze i-voltage transients kunye ne-surges igqithelwe kumhlaba we-subsystem kunye ne-subsystem ngokusebenzisa. izixhobo zokukhusela. umhlaba, ukuze i-voltage edlulayo kunye ne-amplitude ye-surge engena kuwo wonke umatshini kunye nenkqubo iyancipha kakhulu. Umkhuseli wokuqhafaza ubonelela ngendlela elula, eyongayo kwaye ethembekileyo yokukhusela ukukhuselwa kwamandla ombane wezixhobo zombane. Ngokusebenzisa i-anti-surge component (MOV), amandla ombane angangeniswa ngokukhawuleza kwi-induction yombane kunye nokusebenza ngokugqithisileyo. Umhlaba, ukukhusela izixhobo emonakalweni.
