Current Phase Loss
Description
The current phase loss protection function generates the following signals:
-
Alarm: Any of the three-phase currents of the motor goes below 10% of the motor full load current.
-
Trip: Any of the three-phase currents of the motor goes below 10% of the motor full load current for the specified time delay.
-
Current phase loss protection function is not applicable in single-phase mode.
-
Current values that are less than 10% of FLC are considered as stop, and no value is displayed in metering and trip logs.
