Abstract
A transformer configured to receive a primary incoming voltage and provide at least two secondary output voltages. The transformer includes at least one secondary output assembly which includes at least two secondary voltage stabs, the number of voltage stabs being the same as the number of secondary output voltages, connected and configured to provide access to a respective secondary output voltage. The chosen secondary output voltage is connected by coupling a tap change link between a lug landing and either of the at least two secondary voltage stabs. Another of the secondary output voltages is provided by connecting coupling the tap change link between the lug landing and the other of the at least two secondary voltage stabs.
