With the aim of analyzing the ability of vegetable oil-based liquid insulation as alternate medium under moisture-rich environment, this study presents an experimental analysis of impact on breakdown voltage characteristics vegetable oil-based insulating liquids for the moisture inclusion with oil sample. The study has been proposed to carry out with different categories of groundnut oil in crude form, refined form and transesterified form. The moisture inclusion range of 5 ppm to 25 ppm is considered based on the literature with the scope of having lower solubility level and less than 50% of water saturation level for avoiding wet transformer conditions. Experimental investigations have been done on AC breakdown voltage of three categories of groundnut oil for inclusion of proposed range of moisture. With an increased moisture level from 5 to 25 ppm, significant reduction in breakdown voltage of oil samples has been obtained with the average percentage of 53 to 67% which may be due to possible modification in the molecular component of oil with the influence of moisture's polarization characteristics. Based on the experimental observations, the empirical power equations developed based on the regression method to predict the approximate breakdown voltage at different moisture levels.

为了分析在富含水分的环境中植物油基液体绝缘材料作为替代介质的能力，本研究提供了一个实验分析，其对油样中的水分夹杂对植物油基绝缘液体的击穿电压特性产生了影响。已经提出该研究以粗制，精制和酯交换形式的花生油的不同类别进行。基于文献考虑的水分含量范围为5ppm至25ppm，其范围具有较低的溶解度水平和小于50％的水饱和度水平，以避免湿变压器条件。已经对三种花生油的交流击穿电压进行了实验研究，以涵盖拟议的水分含量。随着水分含量从5 ppm增加到25 ppm，油样品的击穿电压显着降低，平均百分比为53％到67％，这可能是由于水分的极化作用可能会改变油的分子成分特征。基于实验观察，基于回归方法建立了经验功率方程，以预测不同水分含量下的近似击穿电压。
