DESIGN AND CONSTRUCTION OF A SINGLE PHASE AUTO-TRANSFORMER OF RATING IKVA, 240V/110, 80 12V, 6V

ABSTRACT This project work-up deals on the design and construction of a single phase step down nations fermor, with raking IKVA, 240V/11OV, 80V 12U, 6V. It is a multi-circuit transformer that has one input as the primary and tappins to produce the output (secondary). It is considered as a single coil in series with the supply and a common coil to the head. It is experimentally done using flat metal shocks of cast steel to form the “E” and “I” shaped laminations and coils of various turns. Not much progress has been made by those who were in the field in the production of a much circuit auto-transformer. While working this project, we got information from some textbooks on auto-transformer and some expert in the field. However, the write up goes beyond the perspectives of an ordinary layman’s belief that the theory behind the construction of an auto-transformer cannot be achieved practically by Nigerian Engineers in this country. Every aspect of the auto-transformer.
