| This article presents results of research and analysis of several measurement methods for determination of electrical, thermal and mechanical parameters of different type of insulation liquids. The main goal of the study is to present procedure that allows the use of the commonly known methods for the analysis of key parameters of new alternative bio-oils. Two scenarios based on different insulation liquids are investigated and compared: petroleum-based insulating oil and NYTRO® BIO 300X insulating bio-oil. It was established that the kinematic viscosity of bio-oil is about twice as low as for petroleum-based mineral oils in the operating temperature area of the insulation. Frequency-temperature dependences of tanδ, permittivity and loss factor of bio-oil impregnated pressboard are determined. According to the results, the use of loss factor to determine moisture content in cellulose impregnated by bio-oil is not optimal. Finally, it is confirmed that in this case optimal measurement method should be based on DC conductivity, AC conductivity and permittivity as input parameters. |
