Description

When power distribution apparatus is diagnosis that utilizes thermal images automatically, there are problems, that there are many thermal patterns similar to the thermal pattern of a target apparatus in a thermal image and temperature around the apparatus influences diagnosis of apparatus. In order to solve these problems, we developed the new method that the apparatus is extracted by using image processing technique based on high order local autocorrelation features, the attachment pattern on a pole, and disparity map, and each apparatus is diagnosed in terms of local temperature gradient. This paper is presented that except for the case that the infrared camera's sensitivity is low, field experiments confirmed that the proposed method can detect faulty apparatuses such as a pin insulator, a section switch and a strain insulator.
