Relation between return voltage and other methods for measurements of dielectric response

Computer simulations, based upon a phenomenological description of the fundamental dielectric processes of conduction and polarisation, have been performed in order to explain the relations between the different methods and to facilitate a better interpretation of experimental results. Experiments have been performed on a 2 m long sample of a 450 kV mass impregnated HVDC cable. In general, good agreement was obtained between measurements and computer simulations
