摘要： A method (100) for determining the operating status of a spring charging motor (10) of a LV or MV switching apparatus (50). The method comprises the following steps: - acquiring a detection signal (I D ) indicative of the behaviour of a driving current (I MOT ), which feeds said spring charging motor during an operation cycle of said spring charging motor; - processing said detection signal (I D ) to calculate a steady-state detection signal (I DSS ) indicative of the behaviour of said driving current (I MOT ) during a steady-state time interval (T SS ) comprised in the operation cycle of said spring charging motor; - processing said steady-state detection signal (I DSS ) to calculate data (DS) indicative of HF and LF spectral components of said driving current (I MOT ) during said steady-state time interval; - processing said data (DS) indicative of said HF and LF spectral components to calculate first and second harmonic distortion values (THD LF , THD HF ), which are indicative of the total harmonic distortion of said LF and HF spectral components, respectively; - processing said first and second harmonic distortion values to calculate first and second output data (O 1 , O 2 ), which are indicative of the variations of said first and second harmonic distortion values with respect to corresponding first and second reference values, respectively. The invention relates also to a diagnostic system (1) implementing said method.

摘要： A magnetic bearing is disclosed that includes a sensing wire wrapped around one or more of the bearing coils and configured to measure the resistance to ground of each bearing coil. With the presence of contaminants such as liquids, a protective coating disposed about the bearing coils degrades over time, thereby reducing the resistance to ground of the bearing coils. The sensing wire transmits the detected resistance to ground of the bearing coils to an adjacent sensing device, which can provide an output that informs a user whether corrective action is required to prevent damage or failure of the magnetic bearing.

摘要： Method for detecting an imminent pole slip of a synchronous generator (2) which is electrically connected to an energy supply network (1), wherein a signal characteristic of a network fault is detected and an imminent pole slip is determined if a load angle of the synchronous generator (2) increases above a predefinable value, wherein the following steps are carried out: - determination of a first load angle (ϑ
OP ) during operation free of network disturbances, - determination of a generator frequency (f
G ) on the basis of the time when a network disturbance occurs, and - anticipation of a second load angle (ϑ
fail ) resulting from the network disturbance by adding the value of the first load angle (ϑ
OP ) to a load angle difference (Δϑ) occurring during the network disturbance, which load angle difference (Δϑ) is caused by a deviation of a generator frequency (f
G ) relative to a network frequency (f
grid ).

摘要： A compressor monitoring system includes current and voltage monitors, current and voltage averaging modules, a control module, and a switch. The current monitor measures a current drawn by a motor of a compressor. The current averaging module generates first and second average current values based on the current measured by the current monitor. The voltage monitor measures a utility power voltage. The voltage averaging module generates first and second average voltage values based on the voltage measured by the voltage monitor. The control module selectively generates a fault signal when a first ratio is greater than a first predetermined threshold and a second ratio is less than a second predetermined threshold. The first ratio is based on the first and second average current values. The second ratio is based on the first and second average voltage values. The switch deactivates the motor when the fault signal is generated.
