Question 1) Draw the circuit diagram of a 3-phase Y-connected voltage source clearly labelling all phase and line voltages. Also, write down the mathematical formulas that express the relationship between phase voltages, and phase and line voltages. Are the line voltages greater in magnitude or phase voltages?

Question 2) Write down the relationship between peak and RMS values of a voltage. What are the peak and RMS values of the mains voltage in Australia?

Question 3) For the following (Delta) connected load, if the phase impedance is 18+21j Ω/Φ, what would be the phase impedance of the equivalent Y (wye) connected load. Draw the circuit diagram of the Y (wye) connected load?

Question 4) What is the current in a 3-phase 4 wire balanced system? and why?

Question 5) What is the per unit system? How are the actual circuit quantities (voltages, currents, impedances, etc) converted to their per-unit values? If the 3-Φ apparent power (|S|) rating of a 3-phase Y-to-Y connected load is 5kVA and line voltage is 415volts, what would be the base impedance?
