“…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.

“…A thermal imaging camera is an instrument that converts the thermal radiation image of the object to be measured into a visible image that can be perceived by the human eye through photoelectric conversion technology [3] . Documents [4][5][6][7][8][9][10][11][12] show that many power supply bureaus and electric power research institutes have used infrared thermal imagers to carry out temperature detection of composite insulator strings, and found many abnormal heating defects of composite insulator strings. At the same time, there are also many high-efficiency institutes that study the heating and defects of composite insulators based on infrared thermal imagers.…”

The scale of China's high-voltage and UHV transmission lines is expanding day by day, and the important components of UHV lines, namely insulator strings, are prone to breakage and self-explosion, which makes the operation of UHV transmission lines have great potential safety hazards. Through the real-time online monitoring of the insulator string of the UHV transmission line, the operation and maintenance personnel are notified in time after the abnormality is found, which can effectively improve the operation reliability and economy of the UHV line. In this paper, we analyze and compare the obvious advantages of various traditional temperature measurement technologies and flexible temperature sensors compared with traditional methods, and propose and introduce an online temperature monitoring system of insulator string temperature with flexible temperature sensing technology combined with modern communication technology, so as to improve the operation and maintenance status of power system network and further improve the automation degree of power grid inspection.
