Assignment of 3-phase Measuring Locations
After determination of the global data, the 3-phase measuring locations must be assigned 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 provides 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. Further-
more, only meaningful setting options appear.
If the global data are implausible, the device does not find any meaningful combination of assignment possi-
bilities. In this case you will find address 230 ASSIGNM. ERROR, which shows one of the following options:
•
No AssigMeasLoc the number of assigned measuring locations is implausible;
•
No of sides the number of sides is implausible
This parameter cannot be changed. It merely informs you about the implausibility of the global settings. If it
appears, you cannot make any further assignments. Recheck in this case carefully the addresses 211, 212, and
213 and correct the settings.
Only one of the variety of the following listed assignment parameter is possible. But in the actual case, only
one address appears, namely the address which corresponds to the above mentioned number of sides and
assigned measuring locations. The measuring location and side are separated by a comma, e.g. 3M,2S means
3 assigned measuring locations at 2 sides.
Only the combinations possible for the number of measuring locations and sides appear as setting options.
The measuring locations of the same side are connected by a "+" sign; the side sequence by a comma. In the
following, all possibilities are explained.
Address 220 ASSIGNM. 2M,2S appears if 2 assigned measuring locations (address 212) have been selected
for 2 sides (address 213). Only one option is possible:
•
M1,M2, i.e. the 2 measuring locations are assigned: M1 to side S1, M2 to side S2.
Since no other possibilities exist there are no further options.
Address 221 ASSIGNM. 3M,2S appears if 3 assigned measuring locations (address 212) have been selected
for 2 sides (address 213). The following options are possible:
•
M1+M2,M3, i.e. the 3 measuring locations are assigned: M1 and M2 to side S1, M3 to side S2.
•
M1,M2+M3, i.e. the 3 measuring locations are assigned: M1 to side S1, M2 and M3 to side S2.
Address 222 ASSIGNM. 3M,3S appears if 3 assigned measuring locations (address 212) have been selected
for 3 sides (address 213). Only one option is possible:
•
M1,M2,M3, i.e. the 3 measuring locations are assigned: M1 to side S1, M2 to side S2, M3 to side S3. This
corresponds to the examples in
The further assignment possibilities can only occur in 7UT635 since 7UT612 provides two 3-phase current
measuring inputs, and 7UT613 and 7UT633 provide a maximum of three 3-phase current inputs (see
Table 2-1).
Address 223 ASSIGNM. 4M,2S appears if 4 assigned measuring locations (address 212) have been selected
for 2 sides (address 213). The following options are possible:
•
M1+M2,M3+M4, i.e. the 4 measuring locations are assigned: M1 and M2 to side S1, M3 and M4 to side S2.
This corresponds to the example in
•
M1+M2+M3,M4, i.e. the 4 measuring locations are assigned: M1 and M2 and M3 to side S1, M4 to side S2.
•
M1,M2+M3+M4, i.e. the 4 measuring locations are assigned: M1 to side S1, M2 and M3 and M4 to side S2.
Address 224 ASSIGNM. 4M,3S appears if 4 assigned measuring locations (address 212) have been selected
for 3 sides (address 213). The following options are possible:
•
M1+M2,M3,M4, i.e. the 4 measuring locations are assigned: M1 and M2 to side S1, M3 to side S2, M4 to
side S3. This corresponds to the examples in
•
M1,M2+M3,M4, i.e. the 4 measuring locations are assigned: M1 to side S1, M2 and M3 to side S2, M4 to
side S3.
•
M1,M2,M3+M4, i.e. the 4 measuring locations are assigned: M1 to side S1, M2 to side S2, M3 and M4 to
side S3.
