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.
