Q. Show Balanced three-phase loads?

Three-phase loads can be connected in either wye (also known as star or Y) or delta (otherwise known as mesh or ). If the load impedances in each of the three phases are the same in both magnitude and phase angle, the load is said to be balanced.

For the analysis of network problems, transformations for converting a delta-connected network to an equivalent wye-connected network and vice versa will be found to be useful. The relationships for interconversion of wye and delta networks are given in Figure. They can be obtained by imposing the condition of equivalence that the impedance between any two terminals for one network be equal to the corresponding impedance between the same terminals for the other network. The details are left as a desirable exercise for the student. For the balanced case, each wye impedance is one-third of each delta impedance; conversely, each delta impedance is three times each wye impedance.
