Undervoltage Protection 27

Funktion
Undervoltage protection consists of three elements (27-1 PICKUP, 27-2 PICKUP, 27 Vp<). Therefore, trip-
ping can be time-graded depending on how severe voltage collapses are. Voltage thresholds and time delays
can be set individually for both elements 27-1 PICKUP and 27-2 PICKUP.
Additionally the element27 Vp< allows the definition of a user defined tripping curve with 20 value pairs
(voltage/ time). Parameterization is done via DIGSI.
