ABSTRACT<\/strong><\/p>\n\n\n\n

This paper presents the development and implementation of a Three-Phase Variable Autotransformer (VARIAC) with a rating of 3KVA and voltage supply of 0-380 volts for a Detachable Machine Trainer. This was born out of the fact that the detachable Machine Trainer bought by my Department for conducting series of experiment in the Electrical power Laboratory lack this vital equipment. The variac core was designed and constructed using circular sheet metal laminations to form a toroid core. Each core (3 for the 3-phases) was then stacked together and fitted with a metal shaft which was connected with three carbon brushes to give the output terminals. The output obtained from the autotransformer was then used to run the detachable machine trainer. The design considerations, calculations, implementation and the results obtained are also presented in this paper. The variac has the advantage of being smaller, lighter and cheaper than typical dual-winding transformers.<\/p>\n\n\n\n
