A method of directly measuring moisture content in an oil-filled transformer (100) includes using an optical fiber (130) that having a grating sensor (140), 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 (120) that surrounds the windings (110). 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.

Systems and methods for ai-assisted electrical power grid fault analysis
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.
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.

A fiber optic accelerometer has a hollow body that supports an optical fiber therein so as to form a cantilever section, a fiber optic splitter coupled to a first end of the optical fiber and a light source for directing light into the optical fiber via a first branch of the optical splitter.

According to one embodiment an apparatus to monitor the temperature of a transformer is disclosed. The apparatus includes a fiber optic cable having a temperature sensing probe on one end embedded in windings of a transformer. An optical converter transmits light to the probe and receives light from the probe, and converts the light received to an electrical signal. The light received back from the probe is controlled by temperature of the probe. Monitors are used to monitor different parameters of the transformer. A controller generates a simulated winding temperature based on data received from the monitors and converts the electrical signal to a direct winding temperature. The controller analyzes the operation of the transformer by comparing the direct winding temperature to the simulated winding temperature. Other embodiments are disclosed herein.

A risk management system includes a plurality of sensors coupled to a processor and to an electrical device, which may be a utility asset, to monitor operational characteristics of the electrical device. The processor may send sensor data and/or processed information to a memory for storage. The processed information, the sensor data, or both are visually and graphically presented in a radar chart, a table, and a sliding scale interface for both selecting data and interpreting data provided by the processor. The combination of the radar chart, the table, and the sliding scale interface allows a user of any level of training or education to quickly and efficiently interpret the sensor data, the processed information, or both with respect to the electrical device. The radar chart depicts a failure profile that provides a visual summary of determined risk scores corresponding to subcomponents of the electrical device that may need investigation, maintenance, or replacement.
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.

RAPID PRESSURE RISE DETECTION AND MANAGEMENT SYSTEM
A rapid pressure rise detection and management system that detects internal pressure changes in a transformer. The rapid pressure rise detection and management system communicates with one or more pressure sensors attached to a tank of the transformer and measures the rate of pressure change versus time. The rapid pressure rise detection and management system then compares this rate of pressure change against a set of parameters to determine if this pressure change is an internal fault requiring the transformer to be taken offline or external fault to be ignored. This rapid pressure rise detection and management system may be a standalone device or work with other monitoring/controlling equipment to expand its sensing and management capabilities.

A method of directly measuring moisture content in an oil-filled transformer (100) includes using an optical fiber (130) that having a grating sensor (140), 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 (120) that surrounds the windings (110). 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.
