To measure phase voltages and currents in a three phase system(engineering students lab report)

Required Components:

AC voltage sources (Vac), resistors (R), voltmeters (Vprint2), ammeters (Iprint), ground (EGnd), and connecting wires.

Circuit Diagram

 this circuit diagram is drawn in pspice  software,you can download free software by clicking links below, to know more about pspice circuit software follow the links below

 

Procedure:

Open Schematics.
Go to get new parts, select and place the required parts. 
Place the components in their appropriate position and if necessary rotate by cntr+r.
Click on draw wire and connect all the elements.
Configure the values of all the placed elements.
Go to analysis, check AC sweep, open it, set total points to 1 and also set the frequency to 50 Hz.
Saves the circuit.
Go to analysis and simulate the circuit.
Go to analysis and examine the results.
