It can be shown that voltages, currents, and impedances in a per-unit system will have the same values whether they are referred to primary or secondary of a transformer. For instance, for voltage, we can prove that the per unit voltages of two sides of the transformer, side 1 and side 2, are the same. Here, the per-unit voltages of the two sides are E1pu and E2pu respectively. Web€8m x $1.25 per euro = $10m. TO THE BASE. Let's look at an example: convert €8m into dollars, using an exchange rate of USD/EUR 0.80. The base currency in the quote USD/EUR 0.80 is the dollar. The quote means $1 = €0.80. We’re converting from €8m to dollars. So we’re converting to the base currency dollars this time. So, we’ll ...
