Lapho i-transformer yamandla isebenza ngokujwayelekile, i- iron core kufanele kube ngokwethembeka kumisiwe ngesinye isikhathi. Uma kungekho emhlabathini, i-voltage yokumiswa yensimbi core phansi kuzobangela ukuwohloka okuphakathi kokuphuma komgogodla wensimbi phansi.

Amathuba okwenza amandla okumiswa kwe-iron core aqedwa ngemva kokuba i-iron core kumisiwe iphuzu elilodwa. Kodwa-ke, lapho umgogodla wensimbi usekelwe endaweni engaphezu kwamaphoyinti amabili, amandla angewona afanayo phakathi kwama-iron cores azokwakha umsinga ojikelezayo phakathi kwamaphoyinti aphansi, futhi abangele iphutha lokushisa okuphansi kwe-multi-point of the iron core.

Iphutha le-iron core grounding ye-transformer lizobangela ukushisa kwendawo kwe-iron core. Ezimweni ezimbi kakhulu, izinga lokushisa lendawo le-iron core lizokhuphuka, igesi ekhanyayo izosebenza, futhi ngisho negesi elinzima lizosebenza futhi lihambe. Iphutha lesifunda esifushane phakathi kwama-chips ensimbi libangelwa izintambo zensimbi zendawo ezincibilikisiwe, okwandisa ukulahlekelwa kwensimbi futhi kuthinte kakhulu ukusebenza nokusebenza okujwayelekile kwe-transformer, ukuze ishidi le-silicon yensimbi yensimbi kufanele lishintshwe ukuze lilungiswe. Ngakho-ke, i-transformer ayivunyelwe ukuthi ibekwe phansi ezindaweni eziningi, futhi iphuzu elilodwa kuphela elingenziwa phansi.
