Oil used in transformer for cooling is crucial for maintaining efficient operation and thermal performance, as it dissipates heat generated during electrical conduction. Unlike dry type transformers, which utilize air for cooling and are typically suited for lower voltage applications, oil transformers are preferred in high-voltage settings due to their enhanced cooling capabilities and ability to withstand higher temperature fluctuations. The oil also provides insulation, thereby reducing the risk of electrical arcing and enhancing safety. While dry type might have lower maintenance costs and environmental advantages, oil transformers generally offer better performance for large-scale applications requiring significant heat dissipation and reliable insulation.
