Abstract: A system is disclosed for detecting the presence of dielectric fluids and water in a utility enclosure. The system includes a sensor assembly that may be installed in the utility enclosure. The sensor assembly has an array of capacitance sensors extending into the utility enclosure to an area where the fluids are expected to be present. The sensor assembly also has a pressure sensor that can detect the total pressure of the fluids in the enclosure. The reading from both sensors can be feed to a processor and a transmitter that sends the readings wirelessly to a receiver assembly. The receiver assembly includes a wireless receiver, a second processor connected to the wireless receiver and a display. The processor may process the readings from the sensors to calculate and report the levels of fluids in the enclosure.

Abstract: The disclosure provides a wireless gauge reader system for use on an existing electrical substation where the substation has a window through which at least one glow tube is visible. The system includes a frame fastened to the substation that surrounds at least a portion of the window, and a door in connection with the frame that allows the door to open and close. The door includes a wireless gauge reader (WGR) that has an optical sensor that is positioned to view the glow tube when the door is closed. The WGR also has a transmitter to transmit a wireless signal based on the illumination state of the glow tube. Various aspects of the connection of the door to the frame are disclosed.
