A device for changing the voltage of [[electricity]].  

This tag is most commonly used to tag distribution transformers, the large cylinders seen on a power and [[utility pole]] to step-down high voltage used in transmission over long distances to the voltage used by the end customer.  It can also be used to tag pad-mount transformers on the ground or other kinds of transformers (e.g. in a detailed image of a [[circuit board]] or other electronics).

Not to be confused with the [[Transformers]], a series about transforming robots.
