	Not a bad definition.  A transformer "works both ways".  In the case of
a distribution transformer intended to "step down" a high voltage to a
low one, the primary is the HV winding.  At the generator the power
"goes in" to the LV winding, which can be called the primary and comes
out the HV winding which can be called the secondary.  I've taken a
number of courses in "power engineering" and don't recall the subject
having been discussed.  A transformer is a transformer and you can use
it as you want.
