Patent ID: 7880575

Claim:
A transformer comprising: a ferromagnetic core with a leg; a high voltage coil mounted to the leg of the core; a low voltage coil mounted to the leg of the core, the low voltage coil comprising a conductor sheeting having opposing first and second ends and opposing first and second side edges; and a coil bus bar having first and second portions and a main section, the first portion having a width that is more than one and a half times greater than a width of the second portion, and the main section having first and second longitudinal edges extending between the first and second portions, the first and second longitudinal edges being non-parallel; and wherein the coil bus bar is secured to the conductor sheeting of the low voltage coil such that: the first portion of the coil bus bar is disposed at the first side edge of the conductor sheeting, the second portion of the coil bus bar is disposed at the second side edge of the conductor sheeting, the first longitudinal edge of the coil bus bar extends perpendicularly between the first and second side edges of the conductor sheeting, and the second longitudinal edge of the coil bus bar faces away from the end of the conductor sheeting.
