Optimization of Bio-based Liquid Transformer Insulator using MOORA Method

摘要

This research investigation was performed to seek the bio-based alternative for the liquid insulator in transformers. The current investigation aims to examine the effect of oil rancidity on the dielectric strength of bio-based oils along with the other preliminary examinations like fire point, flash point, and viscosity. Sunflower oil portrayed the notable performance under all the tests that were conducted. The exposure to the conditioned atmosphere uncovered the presence of a huge variation in DBV of bio-based oil the affirming that the rancidity of oil degrades the insulating ability of the oil. The multi-objective optimization tool MOORA (Multi-Objective Optimization based on Ratio Analysis) was utilized to optimize and select the best oil sample. Upon considering the outcome of all the tests performed and MOORA, sunflower oil was ranked first.
