Claim Text:
1. A system for monitoring a rapid de-excitation system for synchronous machines with indirect excitation, via an exciter machine and a rotating rectifier bridge, comprising: a first measuring device for measuring a current of a stator of a synchronous machine; a second measuring device for measuring a voltage of the stator of the synchronous machine; a third measuring device for measuring an excitation current of an exciter machine; a first device for obtaining an estimated excitation current of the exciter machine from current and voltage values measured in the stator of the synchronous machine; a second device for comparing the measured excitation current Imed with the estimated excitation current Iest, a result of said comparing containing information on a correct or incorrect operation of a rapid de-excitation system, in such a way that:
