Patent GB-1204704-A (GB)
Title: Cable inspection method and apparatus
IPC: G01R31/08
Filed: 1967-08-15
Abstract: 1,204,704. Testing cables. OKONITE CO. Aug.15, 1967 [Aug.22, 1966], No.37557/67. Heading G1U. In an arrangement for testing a cable 2 having insulation a stressing voltage from a source 32 is applied between an internal cable conductor 16 and an electrode external of the cable insulation 10 of such size as to cause some ionization of the dielectric discontinuities within the cable but not to cause corona. The cable is then periodically irradiated by short bursts of penetrating radiation from a pulsed X-ray generator or gamma ray source 6. This causes bursts of corona discharge in the discontinuitites which excite a resonant detector 34. This may operate a marking device 40 and a printer 42 to indicate the position of the discontinuity along the cable. The cable is normally travelling between two reels 4, 8 but full reel testing may be similiarly carried out. This procedure requires a relatively low voltage to be applied to the cable during the production of a corona discharge so that the insulation is not adversely effected and also avoids the production of a continuous corona, which may make discontinuties more difficult to locate. The low voltage may be direct or alternating. To improve the sensitivity of the arrangement a resonant termination 20 is connected to the cable, to eliminate reflection of corona signals by the end of the cable and ensure that they are passed without attenuation to the detector 34.
