Tab. 3-2: Required operations for vector groups with or without zero-sequence current filtering
Vector group matching is via a straight-forward input of the vector group
identification number provided that the phase currents of the high and low
voltage side(s) are connected in standard configuration (see section
Section 3.12.1, (p. 3-63)). For other configurations, special considerations apply
(see Chapter 7, (p. 7-1)). A reverse phase rotation (A-C-B) needs to be taken
into account by making the appropriate setting at the P634. The P634 will then
automatically form the complementary value of the set vector group ID to the
number 12 (vector group ID = 12 – set ID).
