Q1) An abc Y connected three phase source has Vab = 150 – 45°, assume that the source and line
impedances are negligible, we would like to compare to types of connection in a balanced load. We have
chosen to evaluate the circuit using the c-phase which has an impedance Zc = 37 + j28 12
1.1 Y-Y connection.
a) If we connect the load in Y connection, draw the single line diagram of the 2 Points
c-phase and show the voltage and the current at the load.
b) Calculate the real power dissipated at ZCN
