Abstract: A submersible inspection system for inspection of liquid cooled electrical transformers having a wirelessly controlled submersible inspective device. A submersion depth of the submersible can be controlled using a ballast system. The system can also include an input/output selector to switch between camera images from the submersible. A heartbeat signal indicative of a health of the transmitted signal can be transmitted to the submersible, and redundant channel selection logic can facilitate switching to a channel that includes a current heartbeat. A plurality of status interrogation systems disposed on the submersible can capture data regarding inspection procedures performed on the transformer, and the submersible can include tools for repair procedures. Data transmitted from the submersible, and overlayed with input data from an operator, can facilitate real time inspection analysis. The system can also form a model of an internal in the transformer, as well as produce a three-dimensional field of view.

Abstract: A submersible inspection drone used for inspection can include a ballast system used to control depth of the submersible inspection drone. The submersible can be configured to communicate to a base station using a wireless transmitter and receiver. The ballast system can include a pressure vessel for storing fluid and a bag for inflating and deflating as it receives a fluid. Buoyancy of the submersible inspection drone can be provided by change in density of the pressure vessel as a compressible gas is expanded when the ballast bag is caused to inflate or deflate. A pump can be used to draw fluid from the ballast bag and store the fluid in the pressure vessel. In one form the pressure vessel can include a compressible fluid and an incompressible fluid, where the incompressible fluid is used to inflate and deflate the bag.

Abstract: A method of operating a static transfer switch is provided. The method includes monitoring a voltage waveform for each phase of first and second power sources, and calculating flux for each phase of the power sources. The method also includes determining (i) a first flux difference between the respective flux of the first phases of the first and second power sources, (ii) a second flux difference between the respective flux of the second phases of the first and second power sources, and (iii) a third flux difference between the respective flux of the third phases of the first and second power sources. The method further includes turning off a third solid-state switch to disconnect the third phase of the first power source from a load, in response to the controller determining that the third flux difference is greater the first and second flux differences.

Abstract: A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. Multiple light detectors are provided on the charge head to sense light emitted from the vehicle. The system then uses a difference in the amount of light received by different light detectors to determine a direction to move the charge head toward the charge inlet.

Abstract: A charge head is connected to a charge inlet of an electric vehicle to supply an electric charge to recharge the battery of the vehicle. The charge head is attached to a connecting device that moves the charge head to the charge inlet. A sensor is provided to sense the locations of the tires of the vehicle. The system then uses the relative location of the charge inlet to the tires to determine the location of the charge inlet in order to move the charge head.

Abstract: A submersible inspection drone used for inspection of 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 wireless transmitter and receiver. The cameras on the submersible can be fixed in place and can be either static or motion picture cameras. The submersible can include an input/output selector capable of switching between the camera images, either through commanded action of a user or through computer based switching. In one form the input/output selector is a multiplexer. The base station can be configured to display images from the cameras one at a time, or can include a number of separate viewing portals in which real time images are displayed. The base station can include a demultiplexer synchronized to the multiplexer of the submersible.
