S3, M4 to side S4, M5 to side S5.
Assignment of Sides in Auto-Transformers
If auto-transformers are protected the additional question arises how the sides of the protected object are to
be handled by the main protection function, the differential protection. As mentioned above, various possibili-
ties exist how the sides are defined. Further information is necessary in order to achieve an exact replica of the
auto-transformer. Therefore, the following addresses only apply to auto-transformers (address 105 PROT.
OBJECT = Autotransf. or Autotr. node).
