  • Publication number: 20180356457
    Abstract: Partial discharges in a high voltage electric machine can be monitored by a partial discharge monitor connected to the high voltage electric machine successively via a capacitive coupler and a connection cable. The connection cable can have a conductive element designed to self-destruct in the presence of electric current amplitude significantly exceeding expected current amplitudes from said partial discharges, and having diameter designed to avoid creation of additional partial discharges within the cable itself. The connection cable can be light enough to avoid adding excessive weight to the stator windings.

  • Patent number: 7973671
    Abstract: A wireless breakage indicator for a shear pin having an axial bore. The indicator (10) comprises a stem (20) having a head (22) and a foot (24) at opposite ends thereof; a sleeve (32) around a portion of the stem between a first (28) and second (30) axial positions, the stem (20) and sleeve (32) adapted to be broken by the shear pin (12) in the event of its breakage; a spring (26) compressed between the head (22) of the stem (20) and a first end (34) of the sleeve (32); the foot (24) of the stem (20) being retained to the second end (36) of the sleeve (32). The breakage of the stem (20) frees the head (22) to be displaced by the spring (26) and indicate breakage of the shear pin (12). The indication can be direct, by visual inspection of the displaced head, or indirect by the displacement of the head activating a transmitter.

  • Publication number: 20070247613
    Abstract: An optical acceleration sensor includes a target having a reflective portion and a non-reflective portion. A conveyor causes light to be irradiated on the target. A receiver receives light from the target. An inertial mass is coupled to at least one of the conveyor and the receiver, wherein movement of the inertial mass relative to the target causes a change in intensity of an amount of light impinging on the portions to change an amount of light received at the receiver. The conveyor and the receiver may be optical fibers and may be disposed at least partially in an opaque conduit and held substantially parallel in a sensor head.

  • Patent number: 4675664
    Abstract: An antenna receives, by capacitive effect, a current of which the intensity is a function of the distance separating the antenna from an electrical power line. The other factors that influence the current are fixed, constant or are considered negligible. A measuring and conditioning circuit converts the current at the output of the antenna into a coded signal and transmits this coded signal to a control unit. The control unit compares the coded signal to predetermined values stored therein. Alarms are generated by the control unit when the current from the antenna exceeds the predetermined values.

  • Patent number: 4675670
    Abstract: A method and an apparatus for the dynamic and non-contact measurement of the distance separating the surface of a first part that may be conductive or not, from the surface of at least one second conductive part closely spaced from the first conductive part. The method resides in positioning, on the surface of the first part, at least one sensor including two conductive plates that are parallel, superimposed and electrically insulated from one another. The two plates of this at least one sensor are then fed with a same high frequency signal under the same voltage and the current generated by this high frequency signal, between the plate of the sensor which is closest to the surface of the second conductive part and this second conductive part, is measured.

  • Patent number: 4327335
    Abstract: A filtering circuit having the behavior of a low-pass filter capable of having a long time constant. The filtering circuit comprises an input circuit for receiving a voltage input signal to be filtered. A summator circuit is provided for monitoring the input signal relative to an analog output signal from an accumulator circuit and providing an error signal representative of the difference of the input and output signals. The error signal is fed to a voltage controlled oscillator to generate a frequency signal proportional to the error signal. The accumulator has a frequency dividing circuit is provided to divide the frequency signal by a predetermined division factor to control the low cut-off frequency of the filtering circuit whereby to increase the response time thereof. The accumulator also integrates the divided frequency signal. An output circuit provides an output of the stored integrated frequency signal to constitute the analog output signal.
