Abstract (en)
The motor-pump set has a pump (1) driven by an electric motor (2) that is controlled by an electrical circuit (3), where current passing in the circuit exceeds a given threshold during starting of the motor. An activation unit activates an alarm transmitting unit (9) when the current continuously exceeds the threshold for a given period of time, which is comprised between 30 minutes and 24 hours. The activation unit has a current measurement device (5) connected to a comparator (6). The comparator is connected to a clock (8), and compares the measured current with a reference current.
