Partial discharge optical measurement method has strong anti-interference ability and high sensitivity, becoming one of the most important and effective methods to evaluate the insulation condition of electrical equipment, whose signal detection capability is closely related to the layout way of fluorescent fiber sensor. An experimental platform for fluorescent fiber PD detection was built in this paper. The influence of the relative distance between sensor and insulation defect on the PD detection effect was studied in linear layout and Archimedean layout, and then compared with the commonly used UHF method. The results show that the sensitivity of the Archimedes layout is better than the linear layout. When the distance between fluorescent fiber and PD defect is less than 45 cm, the two layout methods of fluorescent fiber sensors have higher detection sensitivity than that of the UHF sensors. For the linear layout, increasing horizontal distance has a more detrimental effect on PD detection than increasing vertical distance. For the Archimedean layout, the lateral offset of fluorescent fiber has a greater effect on the detection PD than the horizontal distance. Finally, according to the characteristics of the two layouts and the location of switchgear where PD is likely to occur, recommendations for placing fluorescent fibers in the switchgear were given.
