When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
What does a VFD do?
Fill in the blank with the correct option: Installing a VFD with a pivot ensures that the _______ at the sprinklers remain constant, thereby maintaining high irrigation uniformity.
Which of the following is not an essential parameter to achieve high uniformity in sprinkler irrigation?
How much energy can you expect to save when installing a VFD with the main pivot?
Fill in the blank with the correct option: VFD provides soft start and soft stop that helps ________.
Test results
Congratulations. You have passed the test and completed the 16 - Monitoring and controls
Achieved badges:
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: A pressure sensor notifies the VFD to reduce the pressure, and thereby the speed of the pump.
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: The pressure decreases in the zone that is open.
Q: When a VFD is installed with a pump, what happens if the valve for one irrigation zone is closed and another is open?
A: The power consumption increases by almost 50% compared with both zones open.
Q: What does a VFD do?
A: It changes the frequency of an electric current supplied to an electric motor
