Figure 2-7 Topology of a transformer bank consisting of 3 single-phase auto-transformers,
topology definitions for a current comparison protection for each phase
Sides:
S1 High voltage side of the auto-connected winding of the main protected object
S2 Low voltage side (tap) of the auto-connected winding of the main protected object
S3 Starpoint side of the auto-connected winding of the main protected object
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
Auxiliary measuring locations, 1-phase, assigned to the main object:
X1 Measuring location, assigned to the main protected object, side 1 and 2
Global Data for 1-
Phase Busbar Pro-
tection If the device is used as busbar protection, either as single-phase protection or as
three-phase protection via external summation transformers, set the number of
feeders of the busbar in address
216 NUMBER OF ENDS
. The minimum number
amounts to
3
ends (with less than that the operation of a 7UT613/63x would not make
sense).
The maximum number of feeders amounts to
9
ends in 7UT613 and 7UT633 and
12
in 7UT635.
Assignment of 3-
phase Measuring
Locations After determination of the global data, the 3-phase measuring locations must be as-
signed to the sides of the main protected object. Only few meaningful combinations
are possible for this assignment because of the condition that always
NUMBER OF
SIDES ≤ No AssigMeasLoc ≤ No Conn.MeasLoc
and that a protected object pro-
vides at least 2 sides. In order to exclude impossible combinations at all, only those
addresses of the following lists are requested which correspond to the global settings
of addresses
211
,
212
, and
213
. Furthermore, only meaningful setting options
appear.
