PROBLEM TO BE SOLVED: To output an oriented value after correcting the difference between a line length settling caused by difference between a transmission line dip or topographical altitude and an actual length. SOLUTION: This device is equipped with an orientation operation part 1 for calculating the distance to a trouble point by using voltage and current data converted into digital quantities and for outputting an oriented value, and a correction calculation part 2 for executing a correction calculation of the difference between a settled electric line length and an actual plane transmission line length relative to the oriented value outputted from the orientation operation part 1. Hereby, as for line length settling, conversion from a plane distance to an actual length is executed before an orientation operation, or as for the obtained oriented value, the actual length is reconsidered to a plane distance to execute the line length settling of the transmission line by treating as a plane length. Therefore, in spite of the difference of treating relative to the line length, that the orientation operation is executed by an actual length, an orientation error caused thereby can be improved, and a trouble point orientation device having higher accuracy can be provided.
