This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:Modelling of migration polarisation, originating as a consequence of a non-uniform electric and thermal stress in electroinsulating systems during operation. Application of the model in cable insulation with variable number of cores in one-phase and three-phase configuration. Verification of the model behavior on specimens subjected to the accelerated ageing tests. Assessment of the ingluence of a non-uniform permittivity and conductivity distribution on service life of systems and their dielectric breakdown strength. Diagnostics of the ageing degree based on measurements of the migration polarisation parameters in the time and frequency domain.
