Application and Setting Notes
Parameter:
Threshold
•
Recommended setting value
(_:1981:3) Threshold
=
10 %
The setting of the parameter
Threshold
depends on the respective application. A threshold value of 10 % is
a practicable value for fault indications of electrical machines.
Parameter:
Operate delay
•
Recommended setting value
(_:1981:6) Operate delay
=
1500 ms
The setting of the
Operate delay
depends on the application. Observe the time grading in the power-
system protection and do not set the time for monitoring too short. The default setting is practicable. For
motors, the time depends on the permissible time period for the set unbalanced load.
Parameter:
Blk. w. inrush curr. detect.
•
Default setting
(_:1981:104) Blk. w. inrush curr. detect.
=
no
With the parameter
Blk. w. inrush curr. detect.
, the stage can be stabilized against tripping on
transformer-inrush currents. If transformers are parts of the protection zones, set this parameter to
yes
.
