For our analysis, we consider a transformer with a peak load between 0.9 to 1.25 its rated capacity to be highly utilized, a peak load between 1.25 to 1.5 to be overloaded and peak load exceeding 1.5 to be critically overloaded. Transformers with loads less than 0.9 are considered to have low to moderate utilization.
