Dropout
The larger dropout differential (= | pickup threshold – dropout threshold |) of the following
2 criteria is used:
Dropout differential derived from the Dropout ratio parameter
If this parameter is not available, a dropout ratio of 95 % applies to the overcurrent protection and a dropout
ratio of 105 % applies to the undercurrent protection.
Minimum absolute dropout differential
Protection-class current transformers
Instrument transformers
Times
Shortest operate time
Operating mode = light only
Shortest operate time
Operating mode = Current and light
90 OOT (Output Operating Time): Additional delay of the output medium used, for example, 5 ms with fast relay, see chapter
