摘要：a circuit (60) is described for the alternating current generator (40) and \\/ or theload of a diesel generator group. a circuit (102) for measuring indications of the level ofcurrent in each phase of the ac generator.it is understood, and a switching circuitdesigned to protect the generator if the current in any phase is higher than a

predetermined level of current in a predetermined time (power surge).or if the current inany phase is less than a predetermined function of currents in each phase in apredetermined time (imbalance). the circuit (60) to protect the ac generator (40),preferably the short-circuit winding inductor ac generator (42).and as it turned off and \\/or closing a fuel valve (35) in order to cut off the motor (20) in the event of a currentoverload or an imbalance is detected. a lock switch and \\/ or installation of circuit breakerto protect the device against shock (85) are also included, together with the protectioncircuit.
