What Is a Transformer Conservator Tank?

UN transformer conservator tank is an oil storage device installed on oil immersed transformers.

Its main purpose is to compensate for the expansion and contraction of transformer oil caused by temperature changes.

The conservator tank helps maintain a stable oil level inside the transformer during operation.

How Does a Transformer Conservator Tank Work?

During transformer operation, transformer oil temperature changes continuously.

When the oil temperature increases:

• transformer oil expands
• oil volume increases
• excess oil flows into the conservator tank

When the oil temperature decreases:

• oil contracts
• oil returns from the conservator tank to the transformer tank

This process keeps the transformer oil level stable.

What Are the Main Components of a Conservator Tank?

A typical transformer conservator tank includes:

• Oil tank
• Oil level indicator
• Breather connection
• Oil filling pipe
• Drain valve

The oil level indicator helps operators monitor the transformer oil condition.

Why Is a Conservator Tank Important?

A transformer conservator tank provides several benefits:

• Prevents excessive pressure inside the transformer tank
• Maintains proper oil level
• Reduces oil oxidation
• Improves transformer service life

Application of Transformer Conservator Tank

Transformer conservator tanks are widely used in:

• Transformateurs de puissance
• Transformateurs moyenne et haute tension
• Outdoor oil immersed transformers

They are an important part of transformer oil preservation systems.
