Manufar da hanyar gwaji na AC jure wa gwajin wutar lantarki na gidan wuta

Gwajin jurewar wutar lantarki na AC gwaji ne wanda a cikinsa ana amfani da wutar lantarki ta sinusoidal power mitar AC wanda ya wuce wasu nau'ikan wutar lantarki da aka ƙididdigewa ga injin da aka gwada tare da bushing, kuma tsawon lokacin shine 1min.Manufar ita ce a yi amfani da wutar lantarki mafi girma fiye da wasu nau'ikan wutar lantarki da aka ƙididdigewa don maye gurbin yawan ƙarfin lantarki da na ciki don tantance aikin insulation na taswira.Ita ce hanya mafi inganci wajen gano karfin insulation na na’urar, sannan kuma wani muhimmin aiki ne na gwaji don tabbatar da aikin na’urar ta lamuni da kuma gujewa afkuwar hadurran da ke tattare da iskar gas.Gwajin jurewar wutar lantarki na AC zai iya gano babban rufin injin ɗin yana da ɗanɗano ne da lahani mai ƙarfi, kamar fashe babban rufin iskar, ƙarancin iska. .Gwajin jurewar wutar lantarki na AC gwaji ne mai ɓarna a cikin gwajin insulation.Dole ne a gudanar da shi bayan wasu gwaje-gwajen marasa lalacewa (kamar juriya na insulation da gwajin rabo na sha, gwajin yatsa na DC, gyara asarar dielectric da gwajin mai) sun cancanta..Bayan an yi gwajin wannan gwajin, za a iya sanya na’urar taranfoma (transformer) aiki.Gwajin jurewar wutar lantarki na AC shine gwajin maɓalli, Don haka, ƙa'idodin gwajin rigakafin sun ƙayyade cewa masu canzawa tare da 10kV da ƙasa yakamata a gwada su don ƙarfin ƙarfin AC bayan shekaru 1 ~ 5, 66kV da ƙasa bayan haɓakawa, bayan maye gurbin windings da kuma lokacin da ya cancanta.
