Abstract
The main goal of this research was the comparison of the impregnation behavior of a new oil, based on the gas-to-liquids process, with a mineral oil, which should be representative for standard mineral oils used in transformers today. The investigation and comparison were made by dielectric measurements with a flat pressboard with a thickness of 0.5 mm and 3 mm as a sample. Additionally wraps with a layer thickness of 6.25 mm, made from kraft paper in cylinders with a thickness of 0.15 mm and an aluminum cylinder as a rack, were investigated. Because of the different geometric shapes of the samples the investigations were made with two different types of electrode assemblies. The measurement of the dielectric dissipation factor was performed with the method of Frequency Domain Spectroscopy (FDS) as well as with the Polarization and Depolarization Current (PDC). The obtained results show that both oils have a similar behavior of the dissipation factor for different samples and temperatures and so they show a similar impregnation behavior. Therefore, it could be considered that the diagnostic methods for dielectric measurements could be also applied to the new GTL based oil.
