Abstract

Abstract: The phase-sensitive optical time-domain reflectometer (φ-OTDR) is proposed to monitor the galloping of the optical phase conductor (OPPC). Optical fiber cables embedded inside OPPC is used as sensing elements. As the exciter of the galloping machine applies different excitation frequencies on the OPPC, the measurement signals of φ-OTDR system are analyzed to figure out galloping characteristics. For different excitation frequencies, the φ-OTDR system measurement signals have corresponding frequency characteristics.

Key words: phase-sensitive optical time-domain reflectometer, optical phase conductor, conductor galloping, optical fiber sensing, transmission line
