In a step-up transformer, conversely, the load is attached across the full winding while the source is connected to a tap across a portion of the winding. Also, a break in the part of the winding that is used as both primary and secondary will result in the transformer acting as an inductor in series with the load (which under light load conditions may result in nearly full input voltage being applied to the output). 1351 JG Almere TEMCo provides first class electrical design, manufacturing, and distribution. In an autotransformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer.
