5.3 Configuration examples
The 7SS52 can be used for protecting busbar confiĆ
gurations with up to 3 main busbars and one transfer
(bypass) busbar or 4 main busbars and up to 48 bays.
For configuration of the up to
D 12 busbar sections (including up to 4 transfer busĆ
bar sections) and
D 12 bus coupler sections
the busbar sections are numbered from left to right
from 1 to 12 and the bus coupler sections from 13 to
24, beginning with the 1st main busbar up to the
transfer busbar or 4th main busbar.
As an example, Fig 5.6 shows the configuration data
for a triple busbar with transfer busbar. For each main
busbar the number of corresponding busbar sections
is parameterized (DA 4900/ZE).
A bus coupler section is a busbar section serving ex-
clusively for coupling busbar sections and containing
no feeders. They normally appear in combiantion with
bus couplers. An example is shown in Fig 5.7.
