Abstract: The present disclosure provides an exemplary three-phase multi-tap balancing distribution transformer capable of operation with both balanced and unbalanced loads and that provides a wide range of incremental voltages to compensate for the varying voltage drops and imbalances as the attached conductor length increases and allows users the ability to incrementally and independently adjust the voltage specifically feeding a specific phase. Incremental adjustment is achieved via the transformer and without any fragile or other external devices or components between the power source and load-side equipment terminals. The transformer, through the use of at least one phase-specific tap-change switch is capable of directly controlling the secondary voltage of the applicable phase independently from the other phases and, thus, does not affect the voltage on the other phases.
