Protective Elements
Example: Transmit Switchgear Position
If it is required to have the switchgear position of the remote side displayed in the local Single Line then this can be
achieved via the Signal Transfer module.
The necessary assignments are shown below as an example.
The “Page Editor” tool has to be used to define an additional switchgear (labeled “QB” in the Single Line diagram of
device A). In this example it is not intended to control the switchgear on the remote side (“Controlled” flag not set =
monitored).
In the “Sig-Trans” module of device A nothing more has to be done than assigning the position signals of the first
switchgear (“QA”) to the transmission inputs (e. g. signal 1 and signal 2).
Then the receive outputs of the “Sig-Trans” module must be assigned to the position inputs of the second
switchgear (“QB”).
Since the assignments are symmetric in this example it is possible to make the same assignments for device B,
with the only exception that in the adapted Single Line diagram of device B, the first switchgear is labeled “QB” and
the first one as “QA”.
