Question

For a specially designed three-phase network, a symmetrical Y-connected resistive load has 20Ω connected in parallel with a symmetrical D‐connected resistive load 40Ω The main voltage of the three-phase network is 363.73V a) Calculate the total line current, IL

b) the parts of it that go to RY=20Ω the load ( IY )

c) the parts of it that go to RD=40Ω the load ( ID )

d) Also calculate the branch current ( IG ) in the D‐connected load.
