Senior thesis, Kansas State Agricultural College, 1908.Introduction: The static transformer is a device used for changing the voltage and current relations of an alternating current. It consists, essentially, of a pair of mutually inductive circuits called the primary and secondary coils, and a magnetic circuit interlinked with both coils. This magnetic circuit is called the core of the transforme
