THREE-PHASE AUTO-TRANSFORMERS

Attention: open in a new window. PDFPrintE-mail

 

Similar to transformers in their construction, auto-transformers differ in the windings since there is no galvanic separation from the supply power.

With the same rated output (Pn), the actual calculation output (Pr) is obtained from the formula:

Pr = (Vmax - Vmin x Pn)/ Vmax
