How Transformers Age | T&D World with conservators as a preventive measure for oil degradation, these transformers were subject to a 40% to 60% load factor when in commission. The degradation rate of a transformer with high-water content in the winding paper (1.5% to 3%) is faster than that of a transformer with low-water content in the paper (less than 1.5%).
