Application and Setting Notes
Parameter: Threshold
•
Recommended setting value
(_:3) Threshold
=
25 V
The
Threshold
parameter is used to set the voltage which the device uses to recognize the calculated fault
voltage (V
F
) as a failure of the voltage sums. Siemens recommends using the default setting.
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.

Voltage Phase-Rotation Supervision
Overview of Functions
The Voltage phase-rotation supervision function monitors the phase sequence of the secondary-circuit
voltages by monitoring the sequence of the zero crossings (with same sign) of the voltages. This enables the
device to detect connections that were inverted during commissioning. The criterion for the check is the
setting of the
Phase sequence
parameter.
Structure of the Function
The Voltage phase-rotation supervision function is located in the Power-system data of each 3-phase
voltage measuring point.
