Depending on its configuration, the device calculates the measured values that are
specific to differential protection.
The differential and restraining values of the differential protection and the restricted
earth fault protection are listed in table 2-16. They always refer to the nominal current
of the main protected object, which results from the parameterised nominal data of the
main protected object (subsection 2.1.5). For multi-winding transformers with different
winding ratings, the most powerful winding is decisive, for busbars and lines the
nominal operation current as set for the protected object. In case of 1-phase busbar
protection, only the values of the connected and declared phase are displayed.
In case of restricted earth fault protection, the nominal phase currents provide the ref-
erence value.
