“…For different types of insulator defects, the characteristic areas of concern are different, and appropriate evaluation indicators need to be determined according to the type of defect. The early decay of composite insulators is often manifested as abnormal heating of the sheath [19][20][21][22][23], and the integrity of the sheath can be used to quantitatively evaluate the infrared inspection image of the composite insulator. The zero-value insulator is mainly manifested as abnormal heating in the steel cap area [24][25], and the inspection image of the zero-value insulator is based on the integrity of the steel cap.…”

In recent years, Unmanned Aerial Vehicle (UAV) technology has been widely used in power transmission line inspection. UAV operating parameters determine the quality of the acquired insulator image, which directly affects the efficiency of transmission line inspection. Regarding the inspection of ceramic insulators, this work establishes a three-dimensional (3D) model of ceramic insulators, and simulates the changes in shooting distance, angle, and height of the UAV through three geometric transformations: rotation, translation, and scaling. The influence of those three UAV operating parameters (the shooting distance, angle, and height) on the integrity of the ce-ramic insulator steel cap is studied. In the infrared zero value detection of 110kV ceramic insulators, It is found that the best setting for obtaining the maximum steel cap area is: shooting distance of 3 -7 meters, shooting height of 1 meter below the center of the insulator string, and a shooting depression angle of 0°. The UAV operating parameters setting method proposed in this paper will provide theoretical and practical basis for the in-depth intelligent inspection of transmission line insulators.INDEX TERMS UAV operating parameters, insulator, zero value defect, infrared detection.

“…However, their high concentration leads to the formation of a luminescence band rather than a stable single photon emitter (SPE), as the defects become too close to each other and become indistinguishable in space. In GaN, VN has been confirmed to cause a green luminescence band [18], while Ni causes a yellow luminescence band [19]. On the other hand, Gai has a high formation energy in N rich conditions, which lead to small concentration.…”

Point defect-based single-photon emitters (SPEs) in GaN have aroused a great deal of interest due to their room-temperature operation, narrow line width and high emission rate. The room-temperature SPEs at the telecommunication bands have also been realized recently by localized defects in GaN in experiments, which are highly desired for the practical applications of SPEs in quantum communication with fiber compatibility. However, the origin and underlying mechanism of the SPEs remain unclear to date. Herein, our first-principle calculations predict and identify an intrinsic point defect NGa in GaN that owns a zero-phonon line (ZPL) at telecommunication windows. By tuning the triaxial compressive strain of the crystal structure, the ZPL of NGa can be modulated from 0.849 eV to 0.984 eV, covering the fiber telecommunication windows from the O band to the E band. Besides the ZPL, the formation energy, band structure, transition process and lifetime of the SPEs under different strains are investigated systematically. Our work gives insight into the emission mechanism of the defect SPEs in GaN and also provides effective guidance for achieving wavelength-tunable SPEs working in fiber telecommunication windows.
