Figure 2-4 Example of a topology on a three-winding transformer
Sides:
S1 High voltage side of the main protected object (power transformer)
S2 Low voltage side of the main protected object (power transformer)
S3 Tertiary winding side of the main protected object (power transformer)
Measuring locations 3-phase, assigned:
M1 Measuring location, assigned to the main protected object, side 1
M2 Measuring location, assigned to the main protected object, side 2
M3 Measuring location, assigned to the main protected object, side 3
Special Considerations on Auto-Transformers
As mentioned above, the common windings on auto-transformers must always be defined as S1 and S2. A
third side may be present if the compensation winding is dimensioned as power winding (tertiary winding)
and accessible (Figure 2-5). In this example we have 3 sides and 4 assigned measuring locations. During para-
metrization of the autotransformer, one must always start with the auto-winding.
