Abstract

Gas pressurization systems are widely used in telecommunication cable networks. These systems maintain the gas pressure in the cable at a higher level than the environmental pressure thus preventing water or moisture from penetrating the cable. This paper proposes a new gas leak location method which employs the pattern matching of transient characteristics while the gas pressure drops
