Siemens SIPROTEC 5 Technical Data

Dropout for Definite-Time Overcurrent Protection Stages
Dropout differential derived from the parameter Dropout ratio
If this parameter is not available, a dropout ratio of 95 % applies for overcurrent/overvoltage and of 105 % for
undervoltage functionality.
Minimum absolute dropout differential
