Here, three phases are shown:- Phase A: Starts from node \( a \) with voltage source \( V_{an} \). It goes through wire impedance \( Z_W \) and ends at node \( A \) with load impedance \( Z_Y \).- Phase B: Starts from node \( b \) with voltage source \( V_{bn} \). It goes through wire impedance \( Z_W \) and ends at node \( B \) with load impedance \( Z_Y \).- Phase C: Starts from node \( c \) with voltage source \( V_{cn} \). It goes through wire impedance \( Z_W \) and ends at node \( C \) with load impedance \( Z_Y \).Each phase has its respective line current \( I_A, I_B, \) and \( I_C \) flowing through the impedances.Nodes \( n \) and \( N \) represent the neutral connections for the source and the load, respectively.
