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.
Claims18
A transformer for providing selectively configurable output voltages, the transformer configured to receive a primary incoming voltage and provide at least two secondary output voltages, the transformer comprising:
- at least one secondary output assembly, the secondary output assembly including:
- at least two secondary voltage stabs, wherein the number of voltage stabs is the same as the number of secondary output voltages, and wherein the secondary voltage stabs are connected and configured to provide access to a respective secondary output voltage of the at least two secondary output voltages;
