HV Cable:
Sheath Test & Fault Localization
HV cable knowledgeSheath test and fault location, course description
The course provides a basic understanding of how to perform a jacket test. In addition, some recommendations for insulation performance values are given.Jacket failure pre-location with bridge principle is reviewed with illustrations. After prelocalisation, the actual location where digging is to be carried out using the step voltage method. This is illustrated with an A-frame and field lines. The step voltage method is discussed with several faults.
