As the system ages under load, the paper and oil can degrade potentially leading to catastrophic failure. Reliable condition monitoring, condition assessment and failure prediction of the insulation system is central to effective transformer asset management and non-destructive/non-invasive approaches are preferred. In this paper we will show that near infrared (NIR) spectroscopy combined with chernometrics is capable of providing rapid non-destructive condition assessment of the paper and the oil components individually.","PeriodicalId":239585,"journal":{"name":"ICSD'01.

The next section discusses more general items and misconceptions on PD diagnostic testing and its role within condition based maintenance (CBM). The section 'Reflection based 0.1 Hz PD test method' summarises the principle of this method. Finally, the section 'Multi sensor 0.1 Hz PD test method' describes a method to meet the challenge of testing long and branched medium-voltage cables.","PeriodicalId":239585,"journal":{"name":"ICSD'01.

The nonlinear behavior of resistivity for electric field is controlled by percolating paths formed by SiC particles.

One way to obtain materials having the desired non-linear characteristics is to use compounds, such as an insulating polymer with a semiconducting filler. A possible filler is silicon carbide (SiC). In this study ethylene-propylene rubber (EPDM) mixtures containing a wide range of SiC particle sizes, from approximately 0.7 to 23 /spl mu/m, have been used to evaluate variations in resistivity, permittivity and nonlinearity. The material properties have been electrically characterized and analyzed both at low voltage in frequency domain and at high voltage in time domain.","PeriodicalId":239585,"journal":{"name":"ICSD'01.
