A mathematical model for estimating the moisture content in silica-gel inside a breather of a power transformer has been developed. The model equations are derived considering the possible real-time operating conditions of the transformer. These operating conditions are the fast rise or decrease of oil temperature due to a step change in the electrical loads and the cyclic heating and cooling of the...
Breather is an important accessory of the power transformer. Among the various sources, breathing is a major source of moisture contamination in the power transformer. A model for estimating moisture content in silica gel and in the atmosphere inside the breather in different mode of working condition of the power transformer is presented in this paper. The proposed model can predicts the failure...
