Siemens 7SJ85 - Application and Setting Notes; Settings; Information List

The functional measured values of Δφ in HMI are displayed differently in the following situations:
•
If the Vector-jump protection function is inactive, the function value of Δφ is displayed as “---”
•
If the Vector-jump protection function is active and has not picked up, the functional measured value of
Δφ is displayed as 0.0°
•
If the Vector-jump protection function is active and has picked up, the functional measured value of Δφ
is displayed as a calculated value (for example, 12.0°) and remains unchanged until the next pickup of
the Vector-jump protection function.
Application and Setting Notes
Parameter: Threshold V1 min
•
Default setting (_:2311:102) Threshold V1 min = 46.189 V
With the parameter Threshold V1 min, you can define the minimum threshold of the voltage band.
The setting value is closed to the allowed lower limit of the voltage band. The default setting is 80 % of the
rated positive-sequence voltage. The value of the rated positive-sequence voltage is 100 V/√3.
Parameter: Threshold V1 max
•
Default setting (_:2311:101) Threshold V1 max = 75.058 V
With the parameter Threshold V1 max, you can define the maximum threshold of the voltage band.
The setting value is closed to the allowed higher limit of the voltage band. The default setting is 130 % of the
rated positive-sequence voltage. The value of the rated positive-sequence voltage is 100 V/√3.
Parameter: T Block
•
Default setting (_:2311:6) T Block = 0.10 s
With the parameter T Block, you set the dropout delay of the Δφ stage.
When voltages are connected or disconnected, the overfunction can be avoided with the timer T Block.
Siemens recommends to use the default setting of the parameter T Block. Keep in mind that the parameter
T Block has always to be set to 2 cycles more than the measuring window for vector-jump measurement.
