<p><P>PROBLEM TO BE SOLVED: To provide a deterioration diagnosing method for efficiently grasping a deterioration condition in a power transmission facility, and for clarifying a criterion for a repair time of metal fittings for overhead wires. <P>SOLUTION: A prediction expression F for the deterioration situation is calculated, based on a deterioration factor E such as line information and wind information, and actual measurement data D in a sampling research for the deterioration condition such as an abrasion in the power transmission facility. The deterioration condition in the power transmission facility is diagnosed from the prediction expression F. The measurement data D are values regarding time. A prediction value calculated from the prediction expression F is a value regarding time. A limit L used in the power transmission facility is preset. A period is calculated as a remaining lifetime until the limit L is attained, based on the limit L and the prediction value found from the prediction expression F. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
