Furan Analysis – Protecting Transformer Paper Insulation

While transformer oil receives significant attention, the condition of paper insulation is equally important. Once paper insulation deteriorates, it cannot be restored. Furan analysis provides valuable insight into its aging process.

What Is Furan Analysis?

Furan compounds are released into transformer oil as cellulose insulation breaks down. Measuring these compounds helps estimate the condition of the paper insulation without opening the transformer.

Advantages

• Non-invasive testing

• Early detection of insulation aging

• Better maintenance planning

• Improved asset management decisions

Supporting Long-Term Reliability

When combined with DGA, BDV, moisture, and acidity testing, Furan Analysis creates a comprehensive picture of transformer health, enabling smarter maintenance strategies and reducing the risk of unexpected failures.
