3-2. Definition and structure
3-2-1. Structural Scheme
In single line diagrams of figures 17 and 18 show, as an example, the basic structure of a standard
equipment and another one with separate bypass line, for a three phase input and output configuration. For
any other configuration, the quantity of cables and terminals at the input, output and bypass will only vary;
internal structure of the equipment will never do it.
