Due to the inherent environmental footprint of petroleum derived transformer fluids, the power industry is gradually exploring the potential of vegetable oils as alternatives. The impetus comes mostly from vegetable oils renewability and their inherent biodegradability. However, the major drawback in the use of vegetable oils as dielectric fluids is their lower oxidative stability and higher kinematic viscosity compared to mineral oils. The results obtained clearly demonstrate the correlation between spectroscopic data induction time, kinematic viscosity, acid value, and peroxide value. Quantitatively, the absorption frequencies of functional groups in vegetable oil transformer fluids that can be correlated to the mentioned quality parameters show noticeable changes with aging/oxidative degradation. The study also demonstrates the utility of integrating spectroscopic data to understand trends in induction time and kinematic viscosity of oil samples heated under transformer service conditions.
由于石油衍生的变压器油对环境的固有影响，电力行业正在逐步探索植物油作为替代品的潜力。这一动力主要源于植物油的可再生性及其固有的生物降解性。然而，将植物油用作介电液的主要缺点是与矿物油相比，其氧化稳定性较低且运动粘度较高。所获得的结果清楚地表明了光谱数据诱导时间、运动粘度、酸值和过氧化值之间的相关性。定量地说，植物油变压器油中可与上述质量参数相关的官能团吸收频率随老化/氧化降解呈现出明显变化。该研究还证明了整合光谱数据以了解在变压器运行条件下加热的油样诱导时间和运动粘度趋势的实用性。
