The permittivity of transformer oil, which is a critical property for its function as an insulating medium in electrical systems, typically ranges from 2.2 to 2.6 relative permittivity (dielectric constant). This value indicates the oil’s capability to store electrical energy in an electric field, directly influencing the performance and efficiency of transformers. Transformer oil also plays a vital role in cooling and protecting the internal components from electrical faults and environmental factors. Proper maintenance, including monitoring the permittivity of transformer oil, is essential to ensure optimal performance and longevity of transformers.
