O le AC tu'ufa'atasi transformers o lo'o fa'aogaina i feso'ota'iga tufatufa fa'atasi ma fa'amauina fa'asologa o le 50Hz ma fa'amauina voltage o le 10kV.E mafai ona fa'aulufaleina fa'ailo fa'amauina o le voluma fa'asologa maualuga ma fa'ailo o lo'o i ai nei ma fa'ailo fa'asolo e leai se fa'asologa o lo'o fa'aogaina e masini fua ma fa'atonutonu.O lenei oloa e iloa ai le tuʻufaʻatasia muamua ma le lua faʻatasi ma tino fesuiaʻi e aofia ai le ZW32, FTU faʻapea foʻi ma isi meafaigaluega, ma faʻatasi ai ma foliga o le laʻititi laʻititi, mama mamafa, faʻatinoga lelei, faʻatuatuaina faʻaogaina, faigofie faʻapipiʻi ma isi.
