TRANSFORMER OIL

The transformer’s core and windings, which are immersed in the oil, are also preserved using transformer oil. The capacity of insulating oil to stop the oxidation of cellulose-based paper insulation is another important quality of transformer oil. The transformer oil functions as a barrier to prevent direct contact between the oxygen in the air and the cellulose, thus reducing oxidation. A magnetic oil level gauge is commonly used to determine the level of transformer oil.

Paraffin-based transformer oil and Naphtha based transformer oil are the two types that are mostly used.

Transformer oil has the following characteristics:

  • Dielectric strength, specific resistance, and dielectric dissipation factor are examples of electrical qualities.
  • Chemical qualities include sludge content, acidity, and water content.
  • Interfacial tension, viscosity, flash point, and pour point are examples of physical qualities.

Testing transformer oil is crucial for:

  • Identifying the fundamental electrical characteristics of transformer oil.
  • Determining whether a particular oil can be used in the future.
  • Determining whether filtration or regeneration is required.
  • reducing the price of oil and extending component life
  • Reducing untimely breakdowns and increasing safety
