Abstract
Power transformers belong to the most important components in the energy transmission and distribution systems. They are using either a solid insulation, or, in case of higher power ratings, a mixed dielectric consisting of paper and an insulation liquid. In the past this liquid was usually mineral oil, but today a lot of different alternatives are available, such as synthetic or natural esters. The breakdown behavior of a needle-sphere electrode configuration especially under impulse stress of these dissimilar liquids seems to be different, leading to another behavior during lightning impulse tests on transformers filled with alternative fluids. Furthermore also the consequential damages of a breakdown seem to be different, thus for mineral oil often an explosion of the tank combined with a pool fire took place, which might be different with other fluids due to their higher flash- and fire-points. Therefore some comparison tests have been performed on different liquids in order to investigate their behavior and the consequences in case of a breakdown.
