Overall dimensions
The main dimensions of the
transformer are
(i)
Height
of window(Hw)
(ii)
Width
of the window(Ww)
The other important dimensions of
the transformer are
(i)
width
of largest stamping(a)
(ii)
diameter
of circumscribing circle
As the iron area of the leg Ai and
the window area Aw = (height of the window Hw x Width of the window Ww)
increases the size of the transformer also increases. The size of the
transformer increases as the output of the transformer increases.
