Porcelain pin insulators are components used to support or suspend conductors and to provide electrical insulation between towers and conductors. The porcelain parts and cast steel of pin-type ordinary ceramic insulators are glued together with cement glue, and the surface of the porcelain parts is coated with a layer of glaze to improve the insulation performance of the insulator. /

The main reason why overhead lines are vulnerable to lightning strikes and pollution flashovers is that the pin insulators of the lines are subjected to pollution and moisture absorption on rainy days, and the insulation level is reduced, resulting in pollution flashovers or breakdowns that eventually lead to line failures. After cracks or serious flaws, pin-type porcelain insulators can sometimes continue to operate in sunny weather, but when encountering light rain or heavy fog, the insulation will drop sharply, which is likely to cause line failure. Therefore, it is an important method to effectively prevent the insulation deterioration accidents of pin insulators by measuring the insulation degree of pin insulators under live conditions and discovering insulation weaknesses.
