From: An intelligent life prediction approach employing machine learning models for the power transformers
2-FAL (ppm) | DP | Physical State (Insulation) |
|---|---|---|
0 ≤ 2-FAL < 0.1 | 1200 − 700 | Fresh (F) |
0.1 ≤ 2-FAL < 1 | 700 − 450 | Lightly Aged (LA) |
1 ≤ 2-FAL < 10 | 450 − 250 | Moderately Aged (MA) |
2-FAL ≥ 10 | < 250 | Worstly Aged (WA) |
