What are the properties of transformer oil?

The properties of transformer oil are critical for its performance in electrical transformers. It acts as an insulator, facilitating heat dissipation and preventing electric discharges. Key properties include high dielectric strength, which indicates its ability to withstand electrical stress without breaking down; good thermal conductivity for effective heat transfer; a wide temperature range, ensuring stability and performance under varying conditions; low viscosity for excellent fluid flow; chemical stability to resist oxidation and degradation; and non-flammability to enhance safety. Additionally, the properties of transformer oil allow it to provide protection against moisture and contaminants, extending the lifespan of the transformer. Proper maintenance and regeneration of transformer oil are essential to preserve these properties for optimal transformer performance.
