Abstract

The ability of locating a degraded portion in a double-core cable insulated with silicone rubber (SiR) or in a coaxial cable insulated with low-density polyethylene (LDPE) was compared between a system based on frequency domain reflectometry (FDR) being developed by the authors and a commercially available system called line resonance analysis (LIRA). Both the FDR and the LIRA methods cannot detect the degradation of SiR before its further use becomes uncommend-able in a nuclear power plant. However, for location trials of the degraded portion in the LDPE coaxial cable, the FDR method showed a higher sensitivity and a better resolution than LIRA.
