3: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
It raises the motor temperature, reducing the lifetime
3: How does over- and under voltage, phase unbalance and phase loss impact the pump motor?
It reduces flow and pressure

4: What can be done to the well if sand continues to enter a well after the well development has been carried out?
The well driller can try to run the pump at its maximum capacity in short periods of time over a couple of days
4: What can be done to the well if sand continues to enter a well after the well development has been carried out?
The well driller can replace the casing with a new one with smaller slots
