Optical fiber sensing technology has the advantages of anti-electromagnetic interference, small volume, multiplexing, etc. Intelligent on-line monitoring for power equipment by optical fiber sensing technology has become a new trend of power grid development. In this paper, the research progress of several optical fiber sensing technologies in the field of power equipment monitoring were reviewed, including fiber grating sensing technology, scattering distributed optical fiber sensing technology, fluorescent optical fiber sensing technology, and interferometric optical fiber sensing technology. From the aspects of temperature monitoring, strain monitoring, partial discharge monitoring, fiber-optic current sensor, pollution monitoring, and hydrogen monitoring, the application as well as the advantages and disadvantages of different sensing technologies in different power equipment were explained. At last, the development direction of the engineering and networking application of optical fiber sensing technology was proposed.
