Abstract (en)
[origin: WO2022162282A1] Device (S) for supervising an electrical system comprising: a redundant rotating electrical machine (M1), at least two independent branches, each one of which comprises: one of the windings of the redundant machine (M1), a control device generating a power control setpoint for controlling the winding, the supervision device (S) comprising the control devices and being configured so as to successively: simultaneously transmit, for at least two control devices of two separate branches, a request for a power test setpoint in addition to the control setpoint, such that the sum of said power test setpoints is zero, and then establishing a fault diagnosis according to measured physical values after the test setpoints have been applied.
