Document Type and Number:
WIPO Patent Application WO/2020/181248
Kind Code:
A3
Abstract:
Systems and methods for the interrogation of an overhead electrical cable using a coherent light source, such as a laser. The systems and methods may include the isolation of one or more optical fibers that are embedded in or attached to a strength member of the electrical cable, and the connection of an interrogation device such as an OTDR device to the optical fibers for the purpose of interrogating the overhead electrical cable to determine a state of the cable, such as temperature or mechanical strain.
