Frequently, in applications calling for simple voltage step-up or step-down,
and where there is no requirement for electrical isolation, applying an
autotransformer will result in significant size and weight reductions as well
as cost. The power rating of an autotransformer is given by the expression:
P
V
V
A rule of thumb to apply when considering an autotransformer is that
the voltage across the entire winding should be less than or equal to
two times (2x) the value of the lowest voltage tap (V

3-Phase toroidal transformers are simply three separate single phase
units. When convenient, they may be mounted as individual units, adding
flexibility to the design of the housing or, in many cases, stacked together
side by side or stacked on top of each other. For higher powered units,
the relative assembly labor is less using toroids where each phase may be
handled separately (usually by one person). Compare this to E-I trans-
former installations where a large single unit must be moved (requiring
several workers and a hoist).
