Kamal Sharma · Answer

High current could be due to following reasons:

1. Discharge valve closed or throttled, water churning.

2. Foreign material getting into the pump, obstructing impeller movement & overloading the motor.

3. Mechanical damage in the pump.

4. Electrical fault in the system, loose connection, start- delta etc.
