Condition evaluation and lifetime strategy of HV cable systems

A suitable remaining life management strategy is crucial for avoiding both premature and delayed decommissioning and replacement of assets, and therefore optimizing their usage. For high voltage underground cable systems, a multitude of different factors from various categories determine their end of life: technical reasons such as ageing and, ultimately, failures are a sufficient criterion and need to be taken into account at all times. This requires a thorough understanding on the underlying physical ageing mechanisms, as well as a reliable and current set of condition data for each asset.
