ABSTRACT:
In a system for recharging electric accumulators, including a polyphase alternator connected to a rectifier circuit, and a voltage regulator circuit connected to the rectifier circuit and the field winding of the alternator, there is connected a circuit for detecting and indicating faults and operating anomalies. This circuit includes a signal processor circuit which is connected to the armature winding of the alternator and is operable to provide an output test signal substantially proportional to the mean value of the signal appearing, in operation, at the actual or virtual star point of the phases of the armature winding of the alternator. Generator means provide first and second predetermined reference output signals. A comparison circuit activates alarm signalling means when the test signal falls below the first reference signal, and when the test signal exceeds the second reference signal.
