Abstract/Summary This paper presents results of dielectric response measurements in frequency domain. obtained at different temperatures for oil-impregnated pressboard samples (new and aged) containing different amount of moisture. Description of the sample preparation and the ageing procedure is also included. The dielectric responses were used for defining master curves and activation energies at the different humidity levels, to be later used in the modelling of diagnostic measurements on transformers. Spread of the results from samples containing similar amount of moisture are also presented.
