IEEE 1234-2019

During the lifecycle of shielded cable systems, failures may occur. In most situations, the system operator locates the failure in order to effect repairs and return the system to operation. Cable fault-locating methods should be chosen to maximize the effectiveness of the fault-locating procedure while minimizing any additional damage to the insulation of the cable system. This guide is intended to be applied to all voltage classes of insulated shielded power cable systems.

This guide is intended to provide troubleshooting and testing personnel with guidance to safely and quickly localize a faulted cable section or locate a cable system fault with minimum risk of further damaging serviceable cables, accessories, and equipment.

Revision Standard - Active. Test and measurements, which are performed on shielded power cables to identify the location of a fault, are described. Whenever possible, the limitations of a particular test and measurement to locate a fault are provided and recommendations are made regarding specialized fault-locating techniques. A fault characterization chart is included as an aid to select a fault-locating technique.
