- •
The relation between the moisture content of the paper and the rate of generation of 2FAL is studied.
- •
A statistical study is carried out using a database with more than 20,000 historical records.
- •
Accelerated ageing tests are carried out on Kraft papers with different moisture contents.
- •
A model is proposed to interpret the 2FAL concentration in differently moisturized transformers.
- •
A comparison with other models in literature is carried out.
