ABSTRACT:
A cable, system and method for detecting partial discharges or arcing in wiring or cables via fiber optics are provided. The cable for detecting partial discharges includes a conductor for carrying electrical signals; at least one fluorescent optical fiber for detecting light generated by a partial discharge; and a first transparent layer surrounding the conductor for supporting the at least one fluorescent optical fiber generally parallel to the conductor. By employing a fluorescent optical fiber, incident light generated by a partial discharge along a length of the optical fiber will be transmitted via the optical fiber to an optical receiver for determining a partial discharge has occurred.
