The behavior of current and voltage in a star connection with resistors atsymmetric and asymmetric load, with and without neutral conductor connection, as well as in a delta connection can be coherently and thoroughly studied and taught.The operating characteristics of the most important transformers, single-phase transformers, single-phase isolating toroidal transformers, single-phase auto-transformers, three-phase transformers at load condition, no-load condition and short circuit, can be safely studied and learnt by means of the experimental transformers.
