Ciao a tutti,

domanda forse banale. Ho un autotrasformatore trifase Input 220V output 400V, se collego il secondario a 380V sul

primario leggo una tensione di 220V ?

Certo, il trasformatore è una macchina statica reversibile!

Se colleghi la 380 ad un avvolgimento in grado di ospitare la 400, in uscita non avrai proprio la 220, ma qualcosina in meno :smile:
