摘要： 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.

摘要： 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.

摘要： 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.
