Siemens SIPROTEC 5 User Manual

Application and Setting Notes for Measuring Point Voltage 1-Phase
(V-1ph)
If you insert a Measuring point V 1-ph in DIGSI 5, you must route a voltage to the measuring point under
Name of the device → Measuring-points routing → Voltage-measuring points.
You can route the following voltages:
•
V A
•
V B
•
V C
•
V AB
•
V BC
•
V CA
•
VN

•
Vx
•
VN broken-delta

Parameter: Rated primary voltage
•
Default setting (_:2311:101) Rated primary voltage = 400.000 kV
The Rated primary voltage parameter is used to set the primary rated voltage of the voltage trans-
former.
If you change the setting of the parameter Rated primary voltage, for example, from 400.000 kV to
300.000 kV using the operation panel, restart the device to ensure that the change of the voltage transformer
ratios was accepted.
Parameter: Rated secondary voltage
•
Default setting (_:2311:102) Rated secondary voltage = 100 V
The Rated secondary voltage parameter is used to set the secondary rated voltage of the voltage trans-
former.
Parameter: Matching ratio Vph / VN
•
Default setting (_:2311:108) Matching ratio Vph / VN = 1.73
With the parameter Matching ratio Vph / VN, you set the deviation between the calculated zero-
sequence voltage and the residual voltage measured directly via a measuring input.
You can find more detailed information in chapter 5.6 Application and Setting Notes for Measuring Point
Voltage 3-Phase (V-3ph).

NOTE
The Matching ratio Vph / VN parameter is only visible in the Measuring point V 1-ph if the voltage
VN broken-delta has been routed.
Parameter: Tracking
•
Default setting (_:2311:103) Tracking = inactive

If you route this voltage, the protection functions operate with the neutral-point displacement voltage.
3
If you route this voltage, the protection functions operate with the voltage measured directly at the broken-delta winding of the voltage
transformer.
