o Short-term overloads possible if thermal limits are not exceeded o Transformer life calculations from IEEE Efficiencies: o DOE Standards 2016 and 2029 o DOE 2016: Applies to low-voltage and medium-voltage dry-type and liquid- filled distribution transformers covering single-phase (10–500 kVA) and three- phase (15–2500 kVA) units with primary voltage ≤345 kV and secondary voltage ≤600 Volts o DOE 2029: Maintains the same general scope but introduces stricter efficiency targets and core material requirements, with a focus on reducing energy losses by 10% to 30% depending on transformer type and size. Increases the transformer's efficiency to 98.95%
