Phetoho ea li-transformer winding ke e 'ngoe ea lintlha tsa bohlokoa ka ho fetisisa.
480V Delta
480V delta transformer secondary e na le li-conductors tsa mekhahlelo e meraro tse hoketsoeng ka tlhophiso ea matsoelintsoeke a kgutlotharo. Mekhoa e tloaelehileng ea delta ha e fane ka ho se nke lehlakore ntle le haeba ho sebelisoa tlhophiso e khethehileng ea motheo kapa setsi.
Litsamaiso tsa Delta li atile kabong ea matla a indasteri moo meroalo e meholo e leng li-motors le lisebelisoa tse boima.
480Y/277V Wye
A 480Y / 277V wye transformer secondary e na le li-conductors tse tharo tsa mekhahlelo le ntlha e sa nke lehlakore. Matla a pakeng tsa li-conductors tsa mekhahlelo e 'meli ke 480V. Matla a tsoang ho mokhanni ofe kapa ofe oa mohato ho ea ho se nke lehlakore ke 277V.
Tlhophiso ena e tloaelehile meahong ea khoebo le ea indasteri hobane e ka sebeletsa lisebelisoa tse peli tsa 480V le mabone a 277V kapa meroalo ea taolo.
A 480v single phase transformer e ka etsetsoa merero e fapaneng. Li-unit tse ling li na le 480V primary le secondary-voltage secondary, tse kang 240V, 208V, 120V, kapa 24V. Ba bang ba ka ba le 480V ea bobeli bakeng sa lisebelisoa tsa karolo e le 'ngoe.
Hore na e hloka ho se nke lehlakore ho ipapisitse le moralo oa bobeli oa matsoeli.
