Figure T3 - Virtual model of a three-phase ≪DELTA-STAR≫ electrical circuit
The model was developed using NI Multisim 14.3. The three-phase voltage/EMF source is connected in delta, and the load is connected in star. This model allows real-time measurement of line and phase currents, phase and line voltages, and active power dissipated in phase loads using virtual measuring instruments. This model is convenient for self-checking during calculations.The model includes microresistors Rg1 = Rg2 = Rg3 = 1 μOhm, connecting opposite phases of the three-phase source. Their inclusion in the model eliminates NI Multisim modeling errors while introducing virtually no error into the simulation results.
