摘要：

The paper presents measurements of relaxation phenomena of sludge layer on the paper in the model of transformer oil gap with PDC (Polarization Depolarization Current). The measurements have been taken at 22 degrees C for various thickness of sludge on a cellulose. The analysis of PDC characteristics showed presence of two relaxation phenomena. For both values of time constants have been estimated. The influence of sludge on the paper surface on the relaxation phenomena has been measured also with FDS (Frequency Domain Spectroscopy) method for a model of OIP bushing. (Influence of sludge on electric processes in paper-oil insulation).
