Patent number: 11933685Abstract: A method of monitoring corrosion of an electrical enclosure in a hazardous environment is provided. The method is implemented with at least one computing device in communication with at least one FBG optical sensor reflecting UV light in the electrical enclosure. The method includes measuring wavelength changes of UV light reflected by the at least one sensor, wherein the wavelength changes are a function of corrosion-related strain in the electrical enclosure. The method also includes computing, by the at least one computing device, the corrosion-related strain in the electrical enclosure based on the measured wavelength changes. The method further includes comparing, by the at least one computing device, the computed corrosion-related strain with a predetermined threshold, and recommending preventive corrosion-related maintenance based on the comparison.Type: GrantFiled: August 20, 2021Date of Patent: March 19, 2024Assignee: Eaton Intelligent Power LimitedInventors: Shubham Kumar, Vikas Pandey, Graig E.

Publication number: 20230207231Abstract: A non-mechanical-interfacing electronic switch or a mechanical-interfacing electronic switch are controlled to modulate between an active state and an inactive state based on electronic action. The switch includes an aperture defining an opening in a housing, and the opening defines an insertion path. A transmitter transmits a signal to a receiver along a signal path. To control the non-mechanical-interfacing electronic switch, a mechanical lockout device having a protrusion is inserted through the opening of the aperture along the insertion path. To control the mechanical-interfacing electronic switch, a mechanical control part have a protrusion is moveable to interrupt the signal. Methods of locking the non-mechanical-interfacing electronic switch with the mechanical lockout device as well as methods of locking the mechanical control part of the mechanical interfacing electronic switch with the mechanical lockout device are also provided.Type: ApplicationFiled: March 10, 2023Publication date: June 29, 2023Inventors: Adam D.
