Scope

Summarizes the main cable monitoring techniques which are currently being assessed worldwide. These techniques are primarily aimed at monitoring degradation of low-voltage cables. Most of the methods are at the development stage and require in-plant evaluation before they could be recommended as standard techniques. The advantages and disadvantages of each method, and its current state of development, are outlined in the following sections. There are two aspects of cable monitoring that need to be taken into account - techniques suitable for ageing evaluation and techniques suitable for monitoring faults in cables. The methods discussed may, in some cases, be more suitable for monitoring faults than for evaluating the degree of degradatin of the cable materials.
