The DL MAC-TT is a multipurpose bench for the study and characterization of single-phase and three-phase transformers of the Eurolab series EM (0.3 kW) and Unilab series UM (1.1 kW).
The transformer is a static and reversible device which transforms the electrical energy from one circuit to another, without any direct electrical connection between two windings and without changing its frequency, with the help of an electromagnetic (mutual) induction.
Single-phase transformers are more popular than three-phase transformers in non-urban areas and are frequently used for power distribution and voltage reduction for residential and commercial applications.
Three-phase transformers are employed typically by electric power distribution grids to power large motors and large loads.
Their main parameters are: operating frequency range, primary and secondary voltage ratings, secondary current rating, operating temperature and power rating (VA).
