In our previous paper, we developed an insulator inspection robot system for a suspension insulator string in the 345kV power transmission line. However, this robot cannot be applied to a tension insulator string, because its constituent insulators are different in diameter and height from those of a suspension insulator string. To solve this problem, we developed a new live-line insulator inspection robot system that is applicable to both suspension and tension insulator strings. We confirmed its effectiveness through live-line performance tests.

A new cleaning robot system for live-line tension insulator string was developed to prevent an insulator failure, which can have severe effects on national security as well as national industry and economy. The robot moves along the insulator string using the clamps installed on its two moving frames. Especially, unlike the existing cleaning robots using jets of water or water/air, the robot system adopts dry cleaning method using a rotating brush and a circular motion guide. This robot system has control architecture consisting of a master control unit and two slave control units. We confirmed its effectiveness through experiments.
