11.13
Instantaneous High-Current Tripping
Setting Values
Threshold value
Dropout ratio
Dropout
The greater dropout differential (= | pickup value – dropout value |) of the following 2 criteria
applies:
Dropout differential derived from the parameter Dropout ratio
If this parameter is not available, a dropout ratio of 95 % applies for overcurrent and of 105 % for undercur-
rent functionality.
Minimum absolute dropout differential
Protection-class current transformer
Instrument current transformer
Times
Operate time for current > 2·√2·threshold value
