Electric wire inspection system, electric wire inspection method, and electric wire

Abstract

An electric wire inspection system and method that can sensitively detect damage on an electric wire, and an electric wire capable of being inspected using the same. The electric wire inspection system includes: an inspection unit which performs electric wire inspection wherein a characteristic impedance between two conductive members of the electric wire is obtained as a response signal by time domain or frequency domain reflectometry; a storage unit which stores the response signal obtained at a first time point; and an analysis unit which retrieves the response signal obtained at the first time point from the storage unit, compares it with the response signal obtained at a second time point later than the first time point, and, if a difference exists between the two response signals, correlates a region in which the difference exists in the response signals with a position along an axial direction of the electric wire.
