Underground Power Cable Failure

Dividing the cable into successively smaller sections will enable you to narrow down the search for a fault. The heat may come from an external source or may be generated by the resistance to current flow in the conductor a particular problem if the cable is overloaded and or underrated for the application. There are two basic methods of locating an underground cable fault.

Underground power cable failure.

Major causes are due to water ingress and poor workmanship. The paper insulation provided inside the cable is hygroscopic in nature. However the detection and localization of cable fault is challenging due to the limited access to the cable burned under the ground. Causes of faults in underground cables most of the faults occur when moisture enters the insulation.

Not all underground cable system failures are due to cable insulation. Heat shrink covers can be used to waterproof these junctions and improve reliability. Excessive heating of the cable will cause degradation of the insulation and sheathing material and premature failure. Open circuits are more common in low voltage cables than at medium or high voltage.

1 risks reducing cable reliability because it depends on physically cutting and splicing the cable. The lead sheath is. The use of underground cables is essential in power distribution networks as they mitigate the issues related to space availability and minimise line breakdown and increase system reliability. Open circuits are usually the result of failed connectors or broken and or corroded conductors.

Other causes include mechanical injury during transportation laying process or due to various stresses encountered by the cable during its working life. Sectionalizing this procedure as shown in fig. Final results of a failure a cable failure almost always exhibits itself as either an open circuit or a short circuit.
