Summary
Stress profiles in HVDC cable systems can differ considerably from the ones seen in AC systems. Ensuring that the tests performed on the system are sufficient to ensure its reliability is a significant concern. This brochure presents a detailed analysis of the parameters that can affect the characteristics of fault waveshapes, as well as it considers the necessity and feasibility of a specific test.
