Amakhoyili okucindezela i-Bias arcziyingxenye ebalulekile ezinhlelweni zamandla, ikakhulukazi ekwehliseni imithelela yamaphutha aphansi esigaba esisodwa.Umgomo wayo wesakhiwo ubandakanya ukuhlelwa kwezingxenye zensimbi ezidonsa uzibuthe ngaphakathi kwekhoyili ye-AC.Ngokusebenzisa i-DC excitation current, amandla kazibuthe womongo angashintshwa, okuvumela ukuthi inductance ilungiswe ngokuqhubekayo.
Lo mklamo omusha wenza ikhoyili yokucindezela i-bias arc iphendule ngokushesha kumaphutha angenzeka kugridi yamandla.Uma kwenzeka iphutha lesigaba esisodwa somhlaba, isilawuli silungisa ngokushesha i-inductance ukuze sinxephezele amandla akhona phansi.Lokhu kulungiswa okusheshayo kusiza ukucindezela i-arcing futhi kuvimbele ukulimala okwengeziwe ohlelweni.
Amasethi aphelele wamakhoyili wokucindezela kazibuthe we-arc ahlinzeka ngezixazululo eziphelele zokuvikela isistimu yamandla.Ikhono layo lokulawula ngokuguquguqukayo i-inductance liqinisekisa ukusebenza okuphumelelayo nokuthembekile ngisho nalapho kwenzeka ukwehluleka okungalindelekile.Lokhu akuvikeli nje izinto zokusebenza kuphela kodwa futhi kuthuthukisa ukuzinza nokuqina kwegridi.
Ukuqonda izimiso zesakhiwo samakhoyili e-bias arc suppression kubalulekile ekuqondeni indima yawo ekuvikelweni kwesistimu yamandla.Ukuhlanganiswa kwesigaba esiwumgogodla ozibuthe kanye nokusetshenziswa kwe-DC excitation current kukhombisa ubunjiniyela obuyinkimbinkimbi ngemuva kwale ngxenye ebalulekile.Ngokuqhubekayo ukulungisa i-inductance, izinselele ezibangelwa amaphutha aphansi esigaba esisodwa zibhekwa ngokuphumelelayo, okunomthelela ekuphepheni okuphelele nokuthembeka kwesistimu yamandla.
Ngamafuphi, ikhoyili yokucindezela i-arc ye-bias iwubufakazi benqubekelaphambili yobuchwepheshe bokuvikela uhlelo lwamandla.Izimiso zayo zesakhiwo kanye nekhono lokuphendula ngokushesha kumaphutha kuyenza ibe impahla ebaluleke kakhulu yokuqinisekisa ukuzinza nokuqina kwegridi.Njengoba isidingo sezinhlelo zikagesi ezinokwethenjelwa, ezisebenzayo siqhubeka sikhula, ukubaluleka kwamakhoyili achemile ekuvikeleni ingqalasizinda ebalulekile angeke kweqiswe.
