Abstract: Among other things, one or more techniques and/or systems are provided for providing recommendations to address design flaws of power system equipment and/or model design flaws for equipment model types of power system equipment. For example, historical sensor data and/or historical field test data, collected from power system equipment, may be analyzed to identify a design flaw of the power system equipment (e.g., a design flaw of a seal ring). A redesign cost to redesign the power system equipment, a failure impact of a failure from the design flaw, a maintenance repair and/or replacement cost, a manufacture alternative component cost to use an alternative component for manufacturing the power system equipment, and/or other factors may be taken into account to crate and provide a recommendation to address the design flaw.

Abstract: A submersible inspection device used for inspection of, for example, liquid cooled electrical transformers can include a number of separate cameras for imaging the internal structure of the transformer. The submersible can be configured to communicate to a base station using a number of wireless transmitters and receivers. Signals transmitted to the submersible include command signals useful to effect an action on the submersible but also a heartbeat signal to indicate health of the transmitted signal. A redundant channel selection logic is provided to switch from a channel which no longer receives a heartbeat to another channel that includes a current heartbeat. Multiple signals can be received and evaluated in software, and another signal received via a firmware radio.

Abstract: A transformer system includes a transformer and a transformer tank. The transformer tank houses the transformer in a bath of a dielectric fluid. The transformer system also includes a controller, and a fiber optic pressure sensor communicatively coupled to the controller. The fiber optic sensor is disposed in the dielectric fluid and operative to provide an output that varies with the pressure of the dielectric fluid. The controller is operative to determine the pressure of the dielectric fluid based on the output of the fiber optic pressure sensor.

Abstract: A method and system for acquiring, manipulating and displaying inspection data obtained by sensors associated with submersible inspection vehicle within a housing having a liquid medium is disclosed in the present application. A control system including an electronic controller is operably coupled with the inspection vehicle and is configured to display data transmitted from the sensor and overlay input data from an operator on the display to facilitate real time analysis during the inspection event.
