Nyob ntawm seb hom transformer, cov tswv yim thiab cov zis windings ntawm ntau theem transformer txuas nrog xws li hnub qub (Y) lossis delta (D) lossis zigzag (Z). Lub kaum sab xis ntawm lub siab voltage thiab qis voltage windings txawv ntawm 0 thiab 360.
Sawv cev raws li vectors, HV winding yog sawv cev raws li 12 (0) teev thiab lwm qhov windings ntawm pab pawg kev sib txuas yog sawv cev los ntawm lwm tus lej ntawm lub moos hauv kev siv rau qhov tiag lossis lub ntsiab lus virtual. Piv txwv li, hauv Dyn 11 kev sib txuas pab pawg HV winding yog delta thiab LV winding yog hnub qub thiab muaj qhov sib txawv ntawm 330 (11x30) ntawm ob lub windings. Thaum HV kawg qhia 12 (0),
LV kawg qhia 11 teev (tom qab 330).
Kev txiav txim siab txog kev sib txuas pab pawg siv tau tsuas yog hauv peb-theem transformers. High voltage winding
yog qhia ua ntej (raws li kev siv) thiab lwm yam windings ua raws li nws. Yog tias cov lus qhia vector ntawm kev sib txuas yog qhov tseeb, tus choj tuaj yeem sib npaug. Tsis tas li ntawd, xyuas cov pab pawg sib txuas lossis polarity yog ua tau los ntawm kev siv lub voltmeter. Direct tam sim no los yog
alternating tam sim no siv tau rau daim tshev no. Cov kev sib txuas ntawm txoj kev hloov tam sim no tau piav qhia hauv cov qauv. Ib qho piv txwv ntawm txoj kev no yog qhia rau ntawm daim duab vector hauv qab no.
Raws li tus neeg siv cov kev xav tau ntawm qhov chaw siv, HUAYI lub tuam txhab tau tsim cov lem ratio tester, uasyog txhais tau rau peb-theem transformers, tshwj xeeb tshaj yog haum rau Z-winding transformers, rectifier transformers,thiab hluav taws xob systems railway Scott, inverse Scott balanced transformers. Input ib theem zog, thiab tsimpeb los yog ob theem ntawm lub zog los ntawm Internal fais fab module, tso zis rau high voltage sab thiab ces coj mus kuaj high voltage thiabtsis tshua muaj hluav taws xob tib lub sijhawm, thaum kawg, cov pab pawg, qhov sib txawv ntawm qhov sib txawv, qhov yuam kev, thiab theem sib txawv yog xam.
