Technologies for the after-laying test of long-distance SF/sub 6/ gas insulated transmission line (GIL) have been developed for the detection of partial discharge (PD) and contact defects. We constructed a long (168 m) test line in a deep tunnel and clarified the propagation characteristics of PD signals through the GIL as well as the spatial sensitivity and S/N characteristics of PD sensors for locating metallic particles. We have also proposed the application of a fiber-optic temperature distribution sensor for locating contact defects and confirmed the validity of this sensor for the GIL test line.
