Abstract
Due to increasing decentralized energy production and rising energy consumption, DC transmission at the MV level is becoming ever more important. The two main advantages are the operational advantages of MVDC transmission
and the higher transmission capacity. To qualify MVAC cables for DC operation, it is important to determine the electrical parameters of the insulation. One key parameter of the DC insulation is the conductivity, which is obtained from LC measurements. Additionally, space charge accumulations can be detected.
In this contribution results from leakage current measurements with varying thermal and electrical stress are presented. Additionally, LC measurements during polarity reversal cycles were carried out.
