A partial discharge detection and localization system for high voltage cable based on a long‐tailed optical fiber Sagnac interferometer has been proposed and experimentally demonstrated. In the system, optical fiber is used as the sensing arm and a piezoelectric transducer is used to simulate ultra‐acoustic signal of high voltage cable partial discharge. Experimental results show that the accuracy of partial discharge localization is 0.016 km. Compared with traditional partial discharge detecting methods, the detection sensitivity can be improved by using the long‐tailed optical fiber Sagnac interferometer.
