Pspice Experiment 2 The following three phase system is a balanced 3-phase system. The elements connected in the manner shown form a Y-Y connected system. In it, voltages V(I), V(2) and V(3) are referred to as the phase voltages. The voltages V(1,2), V(2,3) and V(3,1) are referred to as the line voltages. The nodes connecting the load resistor have been labeled with capital letter, instead of numbers, to help in their identification (it is allowed in Pspice). V1 Rline 1 W 10 A Rload 1 w 100 FREQ = 60HZ VAMPL = 120V VOFF = 0 PHASE = 0 V2 Rline2 Rload B w 10 100 FREQ = 60HZ VAMPL = 120V VOFF = 0 PHASE = -120 D V3 Rline 3 w 10 Rload w 100 FREQ = 60Hz VAMPL = 120v VOFF = 0 PHASE = -240 1) Draw the previous circuit 2) Perform a 34ms transient analysis 3) Obtain a plot of the three phase voltages V(A), V(B), V(C) 4) Are their amplitudes consistent with V(D), V(2), V(3) Discuss 5) Measure the time delays between V(A), V(B) and V(C) and convert them into phase shifts. 6) Make a plot of V(1)+V(2)*V(3). Discuss the resulting plot. 7) Make a plot of I(Rload1)+I(Rload2)+I(Rload3). Discuss the resulting plot. 8) Find the RMS power delivered to Rloadi, Rload2 and Rload3 9) Find the RMS power delivered by each voltage source. 10) Compare the power delivered by the voltage sources with that received by the load resistors. Are they the same? Yes No Why?
