Abstract : This article investigates different currents, voltages, phase differences and powers of sixteen different connections step-down three phase connections transformers fed sinusoidally for analytical and simulation conditions. In this paper, analytical modeling and equations for step-down three phase transformer based on current point signal and voltage polarity are presented. A discussion based on their theoretical use is then presented in the simulation along with calculations regarding their power performances. Results obtained from simulations and analytical situations of sources, transformer primary, transformer secondaries and loads currents (A), voltages (V), powers (W), between sources and transformer primary, between transformer primary and transformer secondaries and between transformer secondaries and loads phase differences were also obtained. These models are also validated by simulation results of currents, voltages, phase differences and powers waveforms for each analytical case. PSpice program is used for this simulation.

Keywords : Transformer Modeling, Polarity. Transformer Simulation, Step-down Transformer.
