Transformer voltage

  1. Apr 24, 2006 #1
    I'm using a 460VAC/230VAC single phase transformer. My customer insists wanting to have 440VAC/220VAC one instead. The ratio between the two transformers are the same. How different are the two? Are they essentially the same ?

    Thank you,

    Both will output the same voltage, which will be determined by the actual voltage input. I'm guessing you are in Europe? The nomial voltage can be either depending on the country (apparently, most are switching to the 460/230 standard). In the US, nominal is 480/240/120.

    The two transformers may have different kVa ratings due to the voltage difference... but if you ratio them to the voltage, I bet you'll find they are exactly the same.
