Application And Setting Notes; Settings; Information List - Siemens SIPROTEC 5 Manual

The phase rotation is important for protection functions which process phase, loop, and directional informa-
tion. You can set the phase sequence with the Phase sequence parameter in the function block General of
the power-system data (see chapter
To supervise the phase rotation, the device compares the measured phase sequence with the set phase
sequence. For abnormal phase sequences, the indication
The connection of the voltages to the device does not depend on the selected phase sequence. The connec-
tion diagrams are shown in chapter
Release Condition
The supervision of the voltage phase rotation is carried out when all measured phase-to-phase voltages are
greater than 40 V.
Blocking of the Function
The following blockings reset the function completely:
•
Via the binary input signal
•
Via a protection pickup
The pickup signal from a protection function blocks the indication
Delay failure indication
When the device detects an inverted phase-rotation direction for the duration of the Delay failure indi-
cation, the indication

Application and Setting Notes

Parameter: Delay failure indication
•
Recommended setting value (_:6) Delay failure indication = 5.00 s
Set the Delay failure indication parameter so that overfunctions due to disturbing influences (such as
switching operations) are avoided. Siemens recommends using the default setting.
