Abstract

Tan δ measurements can be used to assess the condition of OF insulation in HV power cables. Data showing the behavior of tan δ as a function of temperature at constant electrical stress, and as a function of electrical stress at constant temperature, at different stages of degradation (or aging) are essential. By combining on-site and laboratory measurements, the remaining service lifetime of a cable can be estimated for various future loading levels using a model incorporating ground temperature, the age of the cable, and its loading history.
