Dropout
The larger dropout differential (= | pickup threshold – dropout threshold |) of the following 2
criteria is used:
Dropout differential derived from the parameter Dropout ratio
If this parameter is not available, a dropout ratio of 90 % applies to the current threshold values.
Minimum absolute dropout differential
Protection-class current transformers
Instrument transformers
