1. In combination with a power transformer having a primary winding and a secondary winding, a load tap changer (LTC) having a plurality of windings coupled to one of the primary and secondary of the power transformer in order to regulate the output voltage of the power transformer, and wherein the LTC includes a plurality of taps physically and electrically connected to the LTC windings and wherein contact is selectively made to the LTC taps to increase or decrease the output voltage by moving a contacting element from a tap to another tap and the movement of the contacting element is controlled by a rotating shaft driven by a motor, and wherein the shaft may rotate a number of times in going from one tap to the next tap, means for tracking and ascertaining which tap the contacting element is contacting, comprising: means for storing information pertaining to the taps and the number of shaft rotations needed to go from any tap to any other tap; means for sensing and counting the number of shaft rotations causing the contacting element to move from a tap to a next tap; and means responsive to the number of shaft rotations counted and to the stored information pertaining to the number of shaft rotations needed to go from a tap to the next tap for determining that the contacting element has been moved from a tap to the next tap.
