<P>PROBLEM TO BE SOLVED: To obtain a cable run state detection apparatus which is effective for more precisely identifying an accident section without detecting an accident point per se. <P>SOLUTION: A state detection apparatus is mainly composed of a shape memory alloy which is deformed in the region of a temperature difference between during charging of a cable run including a cable 1 and just after break by a breaker while being installed on the cable 1 in a non-contact state. A holding part holding the shape memory alloy in such a state as to allow the deformation while maintaining the non-contact state is provided detachably in the cable 1. The holding part is structured to freely observe the deformation of the shape memory alloy from the outside, and a video image of the shape memory is captured from the outside by a camera 201 and can be stored as digitized captured image data. <P>COPYRIGHT: (C)2013,JPO&INPIT |
