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.
