Application and Setting Notes
Disconnector
The disconnector represents the physical switch in the SIPROTEC 5 device. The task of the disconnector is to
replicate the switch position from the status of the binary inputs.
The Disconnector function block is linked automatically via the information matrix with the binary inputs that
register the switch position and with the binary outputs that issue the switching commands.
The Disconnector function block makes the following settings available (see next table).
Parameters Default Setting Possible Parameter Values
(_:5401:101) Maximum output time
The Maximum output time specifies the duration
of the output pulse created by the switching
command.
10.00 s
0.02 s to 1800 s
(Increment: 0.01 s)
(_:5401:102) Seal-in time
If the target actuating position is not yet attained
although feedback has already been received, the
output time is extended by the Seal-in time. The
Seal-in time is relevant for equipment that sends
feedback before the switching operation is
completely performed. The Seal-in time is only
considered for control models with feedback moni-
toring.
0.00 s
0 s to 60 s
(_:5401:103) Switching-device type
The Switching-device type specifies the type of
the switching device.
disconnector switch-disconnector
disconnector
grounding switch
fast grounding switch
NOTE
The parameter Switching-device type is effective only on the IEC 61850 interface. This parameter is
used to set the disconnector switching device type for communication via IEC 61850. It is a mandatory data
object in the IEC 61850 standard.
The following figure shows the logical inputs and outputs of the Disconnector function block.
