Abstract: The invention relates to a method and system of monitoring partial discharges occurring in an electrical system, and to a method of measuring or analyzing partial discharges occurring in an electrical system. The method comprising receiving a signal or impulse, or information associated therewith, from the electrical system; breaking the received signal or impulse into predefined frequency components; and displaying a peak of the received signal or impulse on a scatter plot with other peaks associated with similar predefined frequency components.

Abstract: This invention relates to high voltage electrical or power systems and in particular to a method and device for monitoring partial discharges in high voltage electrical or power systems. The method comprises defining a low trigger level and a high trigger level electrical pulse amplitude levels, monitoring at least one phase of the electrical system for an occurrence of a pulse within a defined minor time frame; detecting a peak amplitude of a pulse occurring in the electrical system within the minor time frame; determining if the detected peak amplitude of the pulse exceeds the lower and higher trigger levels; assigning a pulse number to the pulse if the peak amplitude of the pulse exceeds the trigger levels; capturing the pulse if the pulse number associated with the pulse is less than a predetermined pulse number threshold in the minor time frame; and storing the captured pulses in a memory.

Abstract: The invention relates to a cover 1 for an aperture in a wall, in particular a vehicle wall, for a rod-like force-transmitting means, in particular a handbrake lever. The cover has an opening region 2 with a through-opening 3 through which the force-transmitting means can pass and a support region 4 for supporting the cover on the wall. For adaptation to a change of position of the actuated force-transmitting means at least in a plane of movement at least approximately perpendicular to an opening axis a of the through-opening 3, the opening region 2 of the cover 1 can be coupled to the force-transmitting means in a movement-effecting manner such that its position can be changed with respect to the aperture. For planar covering of the aperture there is provided a flexible wall element 10 which is connected to the opening region 2 and to the support region 4 or is connectable to the opening region 2 and to the aperture, and which covers at least a gap between support region 4 and through-opening 3.

Abstract: A method of and system for processing stray flux data associated with a synchronous electrical machine; the method comprising capturing stray flux data from the synchronous electrical machine; generating a stray flux waveform using at least the captured stray flux data; analysing the generated stray flux waveform and the captured stray flux data; and storing the generated stray flux waveform and the captured stray flux data in a database.
