Dropout
The larger dropout differential (= | pickup value – 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 overvoltage protection and a dropout
ratio of 105 % applies to the undervoltage protection.
