A system for indicating the position of a tap of a voltage regulator system. An electrical signal representing the tap position is converted to a digital format and provided to a processor which controls an electronic display. The display provides a graphical representation of the tap position. As the tap position changes, the processor samples the tap position data and upon determining that the tap has settled at a position, updates the display accordingly. The processor also keeps track of the minimum and maximum tap positions and displays those as 'drag-hand' positions on the tap position display. The displayed 'drag-hand' positions are reset in accordance with a signal received from a user-operated reset switch. The tap position indication system can also communicate tap position information via a data port and provide variable-amperage control. The data port can also be used to reset the 'drag-hand' positions and to communicate variable-amperage information and settings (e.g., raise and lower limit settings).
