Research Summary

Transformer oil, also known as insulating oil or dielectric oil, is a specialized oil used in electrical transformers and other electrical equipment to provide insulation and cooling. It serves multiple functions, including preventing electrical discharges, suppressing arcing, and dissipating heat generated during the transformer＇s operation. Transformer oil is typically a highly refined mineral oil with excellent electrical insulating properties and thermal stability. In addition to its insulating role, transformer oil acts as a coolant, carrying away heat from the transformer＇s core and windings. It undergoes strict quality control measures to ensure low moisture content and high dielectric strength. Periodic testing and maintenance of transformer oil are essential to monitor its condition, detect potential issues, and ensure the reliable performance of electrical transformers in power distribution networks.
