Mathematical Design and Numerical Optimization of additives in Transformer Oil using RSM CCD

The addition of antioxidants to the Transformer Oil (TO) is increasingly important due to its benefits during the operation of transformers. Despite its excellent dielectric function, the liquid insulation deteriorates by temperature and moisture. The over-addition of antioxidants (Ax) leads to agglomeration and the less-addition leads to poor dielectric properties. However, to keep the Primary Ax (PriAx) and Preventive Ax (PreAx) in phase with the TO, this method uses an emulsifier and stabilizer called Lecithin (Ln). To find the optimal addition of additives this method uses Response Surface Method (RSM) – Central Composite Design (CCD). The overall proposed method mathematical designs and evaluate the generated models. The optimal solutions are obtained using numerical optimization attempt and thereby creating 2D design spaces. Hence, this method provides both desirability and credibility.
