Grade of transformer oil

Question

Accepted Answer

Transformer oil is graded based on its dielectric strength and viscosity.

Transformer oil is graded based on its dielectric strength, which indicates its ability to insulate and protect the transformer from electrical breakdown.
The viscosity of transformer oil is also an important factor in determining its grade, as it affects the flow and lubrication properties of the oil.
Common grades of transformer oil include mineral oil, silicone oil, and synthetic esters.
Higher grade transformer oils typically have higher dielectric strength and better thermal stability.
Regular testing and monitoring of transformer oil is essential to ensure optimal performance and prevent equipment failure.
