phase concatenation (D windings). For standard vector groups, this information corre-
spond to the ends of the windings. In more unusual vector groups (which are created
by phase swapping), the phase assignment in the vector group is not always clear.
The thermal values are referred to the tripping temperature rise. For degrees of tem-
perature there are no referred values. However, since further processing of such
values (in CFC or when transmitted through serial interfaces) requires values without
dimension, arbitrary references have been chosen, which are contained in Table 2-15
in the column „% conversion“.
Table 2-15 Thermal Measured Values

3)
only if RTD box(es) available
