Abstract
The authors have demonstrated that the estimation of the precise locations of points in cables aged thermally or mechanically or by the irradiation of gamma rays is possible by a combination of frequency domain reflectometry (FDR) and inverse fast Fourier transform (IFFT). This paper examines how this ability of fault location depends on the type and structure of the cable, using several kinds of polymer insulated cables such as triple core cables insulated with flame-retardant ethylene propylene diene copolymer (FR-EPDM), dual core cables insulated with silicone rubber (SiR) or crosslinked polyolefin (XLPO), and coaxial cylindrical cables insulated with low density polyethylene (LDPE). As a result, for cables with lengths of 16 to 72 m, the maximum sensitivity is attained when the highest frequency of the inputted electromagnetic waves is 1.0 GHz or higher for coaxial cables, but around 600 to 800 MHz for dual or triple core cables.
