3-HANYA MAI CIN TSORON SAUKI

3-phase transformers yawanci suna da aƙalla windings 6- 3 firamare da 3 na sakandare. Ana iya haɗa iska ta farko da ta sakandare a cikin jeri daban-daban don biyan buƙatu daban-daban. A cikin aikace-aikacen gama gari, yawanci ana haɗa iska a cikin ɗayan shahararrun saiti biyu: Delta ko Wye.

DELTA CONNECTION
A cikin haɗin delta, akwai matakai uku kuma babu tsaka tsaki. Haɗin delta mai fitarwa zai iya ba da kaya mai matakai 3 kawai. Wutar lantarki (VL) daidai yake da wadatar wutar lantarki. Matsayi na yanzu (IAB = IBC = ICA) daidai yake da layin yanzu (IA = IB = IC) wanda aka raba ta √3 (1.73). Lokacin da aka haɗa na'ura mai canzawa zuwa babban kaya mara daidaituwa, matakin farko na delta yana samar da ingantacciyar ma'auni na yanzu don tushen wutar lantarki.

WYE CONNECTION
A cikin haɗin wye, akwai matakai 3 da tsaka tsaki (N) - wayoyi huɗu gabaɗaya. Fitar da haɗin wye yana ba da damar taransifoma don samar da wutar lantarki mai lamba 3 (phase-to-phase), da kuma ƙarfin wutar lantarki don ɗaukar nauyin lokaci ɗaya, wato ƙarfin lantarki tsakanin kowane lokaci da tsaka tsaki. Hakanan za'a iya shimfida wurin tsaka tsaki don samar da ƙarin aminci lokacin da ake buƙata: VL-L = √3 x VL-N.

DELTA / WYE (D/Y)

Tsarin delta na farko da na sakandare na wye (D/y) ya fito fili don iyawarsa don isar da daidaitaccen nauyin wayoyi uku zuwa kayan aikin samar da wutar lantarki, yana ɗaukar aikace-aikace daban-daban ba tare da matsala ba. Ana zaɓin wannan ƙa'idar akai-akai don samar da wutar lantarki zuwa sassan kasuwanci, masana'antu, da manyan wuraren zama.
Wannan saitin yana da ikon samar da nau'ikan nau'ikan nau'ikan nau'ikan 3 da nau'ikan lokaci guda kuma yana iya ƙirƙirar tsaka tsakin fitarwa na gama gari lokacin da tushen ya rasa. Yana hana surutu (harmonics) yadda ya kamata daga layi zuwa gefe na biyu.
