Sažetak
The aim of this research is to develop a physical model useful for measuring the influence of ageing, temperature and water content on the high voltage behavior of oil-paper insulation. The insulation model, made in accordance with the instrument transformer design practice, is placed in a specifically designed capsule in which those parameters can be controlled. All the parts of the capsule were electrically optimized using finite element method-based software. A procedure for insulation preparation that quantifies the water content has been developed. The partial discharge tests verify the applicability of the designed capsule. Thermal testing verifies the model’s useful temperature range up to 120 °C.
