Monitoring of supply pumps
- Product category:
- Monitoring and
- Conveyor and transport systems
- Ensuring the correct rotation direction for the supply pump in a hydropower plant.
- By monitoring the connected phases for failure and phase sequence, any error status is detected.
If the the rotating field is connected incorrectly when the pump is put into operation, the supply pump does not start.
The rapid detection of phase failure must be ensured in order to prevent the motor and thus the pump from being damaged.
- - Prevention of overload in the event of incorrect running direction and shutdown
- Safe detection and shutdown in the event of phase failure
