Resumen
Monitoring system for short-circuit detection of a switching element of a rapid de-excitation system for synchronous machines with indirect excitation. Monitoring system for detection of short circuit of a maneuver element of a rapid de-excitation system for synchronous machines with indirect excitation (1) through an exciter machine (2) and rotating rectifier bridge (8), characterized in that it comprises: - a subsystem for measuring the evolution of the stator voltage (13) of the synchronous machine (1); - a data processing subsystem for obtaining the de-excitation time (17) from the evolution of the stator voltage; - a subsystem that compares the time obtained with an adjustable threshold time by means of a time comparison system (20) so that: - in case of correct operation of the system and/or of the maneuvering element, the time obtained is less than the previously set time; - in case of incorrect operation of the system and/or of the maneuvering element, the time obtained is longer than the previously set time.
