Stage with Definite-Time Characteristic Curve

Setting Values
Method of measurement
Threshold value
Dropout ratio (fixed)
Time delay
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
