Sensors of the rotor vibrations measure a relative distance of a revolving turbine rotor and a stator. A trajectory of eccentric rotor motion is reconstructed by combination of measured distances in an orthogonal coordinate system. The trajectory of rotor motion is divided into individual orbits. Each orbit includes information about orbit origin coordinates in an orthogonal coordinate system at the beginning of the rotor revolution. An initial amplitude and an initial angle from the origin of the orthogonal coordinate system are determined for each orbit. The development of change to coordinates of the orbit origin over time is monitored by monitoring the change value of the initial amplitude values and change of the initial angle between the consecutive orbits. The synchronous rubbing is detected by the development of change of the initial angle counter the rotor rotation direction and by exceeding of the threshold values of the initial amplitude, initial angle, and the area under curve defined by coordinates of the origins of consecutive orbits, in a determined unit of time.

When monitoring turbine blade vibration, the turbine rotor vibration is measured using at least one rotor vibration sensor located on at least one turbine bearing. The signal obtained is preprocessed by converting it from the time domain to the frequency domain (preferably by a discrete Fourier transform), the wide band spectrum noise level of signal is suppressed (preferably by liftering the signal cep strum) and the variance of the wide band spectrum signal noise is suppressed (preferably by averaging the liftered spectra of the signal). Subsequently, the components of the blade vibration in the preprocessed signal are identified. The identification includes the process of thresholding the preprocessed signal and clustering the components from the thresholding. The identified blade vibration components are then monitored for the magnitude of deviation in frequency and/or amplitude of at least one identified component from its nominal state.

The output shaft (6) of the gear (5) is a part of the next following gear (7). Output shaft of this gear (7) can be connected either directly or by using the coupling (12) to the axle (8) of the traction vehicle, or to the wheel (9). Alternatively, in case the higher transmission ratio is required, it can be connected to another gears (10), where the output shaft of the gears (10) is connected to the wheel (9), or to the axle (8) of the traction vehicle directly or by using the coupling (12). The drive unit can be equipped with brake (13).

A method of, and arrangement for, producing shaped hollow metal objects by a hot process. A metal hollow semi-finished-product with at least one opening is heated to a forming temperature and placed into a cavity, whose shape corresponds to the desired final external shape of the hollow object. Then the cavity is sealed and water and/or steam is introduced therein. After the final shape of the semi-finished-product is achieved, the semi-finished-product is removed. The cavity is formed by a split mould, whose opening's entry edge has an expanded portion, against which a sealing feature is oriented. The outer surface of the sealing feature is arranged to close against this expanded portion. The sealing feature is also provided with a means of supply of water and/or steam, and a tube through which the water and/or steam is supplied. This tube extends into the interior space of the semi-finished-product, and can be provided with nozzles.

The rotor of the turbine is monitored by sensors of the rotor vibrations arranged in at least one plane of measuring perpendicular to the axis of the rotor and by sensors of the absolute vibrations of the bearings. When using this method of processing, synchronically digitalized signals of the sensors of rotor vibrations, first the arithmetic mean of the individual harmonic bands in full spectrum in the frequency domain is calculated, by which means the information about the subharmonic components and their multiples in the full spectrum of these signals is transferred into the frequency band −1X to 1X, at the same time is by the calculation of the median estimated the level of the signal noise, with which individual frequency bands of the full spectrum are encumbered, and which is subtracted from the amplitudes in the individual frequency bands of full spectrum of the signals of the sensors.

The apparatus represents a controlled current source (1) that is connected in-between a transformer neutral point (3) and the earth potential. It works not only as a compensator of ground fault currents and higher harmonics of fault currents at the point of the ground fault but is also used for compensating phase non-symmetry during a trouble-free state of the distribution system. The function of a controlled current source (1) may be performed for example by a voltage source inverter, current source inventer or frequency converter.
