Advanced Cable Monitoring Techniques For Earlier Failure Warning

In this paper we discuss the limitations of conventional online monitoring technologies for underground cable systems. We highlighted the need for earlier warning of more failure modes in more locations which can be missed by online DTS or PD monitoring, but are now visible through DES over fibre. This passive sensor technology is capable of monitoring electrical and thermal stresses at vital locations which lead to asset degradation and failure, seen only later by conventional online techniques.
