The purpose of transformer impregnation is to enhance the insulation performance of the transformer and protect its internal components. Here are the main objectives and benefits of impregnation:

Insulation Protection: Impregnation creates an insulating layer both inside and outside the transformer, preventing moisture, impurities, and contaminants from entering the transformer's windings and other critical components. This helps prevent degradation of insulation materials and electrical faults.

Temperature Stability: The insulation materials used in impregnation typically have excellent heat resistance, helping to stabilize the operating temperature of the transformer. This is crucial for transformers operating under prolonged or high-load conditions, as elevated temperatures can lead to aging and failure of electrical insulation materials.

Improved Insulation Strength: Impregnation can enhance insulation strength, reducing the risk of electrical breakdown between internal components of the transformer. This helps ensure safe and effective operation of the transformer during its service life.

Corrosion Prevention: Impregnation protects the metal components of the transformer from corrosion. Impregnation typically involves the use of oil-based or resin-based materials that form a protective coating, extending the transformer's lifespan.

Noise Reduction: Impregnation can also reduce noise generated during transformer operation by absorbing vibrations and sound.

In summary, impregnation is a critical process used to improve transformer performance, maintain and extend its lifespan. It helps ensure that transformers operate reliably in various environmental conditions while reducing maintenance costs and the risk of failures.
