Transformer Lifetime Prediction - Stanford University· PDF fileDP degradation curve for an ideal transformer is shown below. We assume that the initial value of DP is 1000. The threshold DP below which the transformer ceases to function is assumed to be 250. 1 day is treated as 1 time step. As can be seen from the curve, an ideal transformer, with these parameter settings, lasts for about 2931 days.
