  • Publication number: 20240133936
    Abstract: A system and method of automatically detecting electrical discharges in a gas insulated switchgear equipment and locating the electrical discharges in real-time is disclosed. The method includes sensing an ultra high frequency (UHF) signal generated from the electrical discharges at multiple channels simultaneously. The UHF signal sensed at multiple channels are reviewed simultaneously to determine whether they are of the same electrical discharge or not. The method also provides the sensed UHF signal at multiple channels to an artificial intelligence training model trained to determine the type of electrical discharge such as a partial discharge or an arc. The method provides a location of the electrical discharge based on an attenuation profile associated with the multiple channels and other information including amplitude information and distance information between adjacent channels.

  • Publication number: 20240022835
    Abstract: A method and apparatus (e.g. circuitry) provide high-speed charge-coupled CMOS TDI imaging based on the parallel readout operation of multiple TDI stages. A plurality (N) of output registers are reset and precharged globally in parallel ready to take charge transferred from the same number (N) of the TDI pixel registers. Each of the signal charges at respective output registers is converted to a signal voltage in parallel. Each of the analog signal voltages is then converted to a digital value in parallel by each of the number of the ADCs. The AD conversion is also performed in parallel while the next N number of the TDI registers is processed. The N output registers are linked to receive the charges from a beginning of the registers along to an end. Converting the respective signal voltages is performed by S/H capacitor array circuitry in a ping-pong fashion using CDS voltages.

  • Publication number: 20230353908
    Abstract: Provided are apparatus, methods and techniques to perform a readout of a plurality (N) of Time Delay and Integration (TDI) pixel registers to receive respective signal charges at a plurality (N) of sense nodes (SNs). The readout uses a plurality (N) of charge steering (CST) gates to steer and demultiplex respective charges from respective pixel registers to corresponding SNs. Output is provided from the SNs for producing respective digital values (e.g. through parallel conversion using ADCs). In an embodiment, charges are transferred vertically to the CSTs for demultiplexing horizontally to the SNs. The CSTs may be configured in a multi-stage configuration to assist with good charge transfer. The CSTs may be associated with a barrier implant to assist with proper charge steering.

  • Patent number: 11735912
    Abstract: Systems, methods, and processor-readable storage media for AI-assisted electrical power grid fault analysis predict the cause of a fault and cause the fault to be remedied by receiving an indication that a first fault has occurred, identifying a plurality of additional fault records associated with the first fault, obtaining a first prediction of the cause of the fault based on the first fault record and the plurality of fault records by applying the fault records to a machine learning model, obtaining a second prediction of the cause of the fault by applying the fault records to a rules-based model, and obtaining a final prediction of the cause of the first fault based on the first prediction and the second prediction. The final prediction of the cause of the first fault is used to cause the predicted cause of the first fault to be remedied.

  • Publication number: 20230175954
    Abstract: A method of directly measuring moisture content in an oil-filled transformer includes using an optical fiber that having a grating sensor, such as a Fiber Bragg grating, defined in the optical fiber. The various conductors (windings) in the transformer are insulated using an insulator such as paper and insulating oil is filled inside the transformer. Moisture in the transformer is absorbed by the paper that surrounds the windings. A moisture content at a specific location can be measured by placing the optical fiber with the grating sensor directly at the specific location to be measured. A physical parameter of the paper that absorbed moisture changes over time, causing a change in the grating sensor of the optical fiber which changes the spectral response of optical signals that are reflected by the grating sensor. The method provides an accurate method of measuring the moisture inside the transformer at the specific location.

  • Publication number: 20230036218
    Abstract: Systems, methods, and processor-readable storage media for AI continued learning in electrical power grid fault analysis use historical fault record data to generate a fault cause prediction model for predicting the cause of a fault, and modify the fault cause prediction model based on additional technician data received from power grid technicians. The systems disclosed herein additionally receive an indication of a fault which has occurred in a power grid, obtain a prediction of the cause of the fault by applying the indication of the fault to the fault cause prediction model, and cause the predicted cause of the fault to be remedied.
