In addition to the higher capital cost of oversizing, the cost of operating a lightly loaded transformer is also higher. Using the Cadmus survey findings, Figure 1 shows that the efficiency of a typical 75kVA, NEMA TP 1 transformer, with a required efficiency of 98.0% at 35% FL, is 97.4% at 17% FL, but only 95.9% at 9% FL.

This is the voltage supplied to the primary of the transformer. For example, if a 75 kVA transformer is connected between one-phase and neutral of a 13.2/22.9 kV three-phase system, the single-phase voltage is 13.2 kV. For an open Delta system where the voltage between phases is 22.9 kV, the single-phase voltage is 22.9 kV. Example for Chart 2
