1.1 We have two loads in delta and another in star in parallel, the impedances of the branches of the delta are equal and we have that RΔ=1p.u. and XΔ=0.75 p.u., while in the star we have equal values of the branches, but formed by admittances where we have the conductance in parallel GY=0.64 p.u. and inductive susceptance of BY=-j0.48 p.u. If the loads are being supplied by a positive sequence balanced three-phase source with line-to-line voltage of phases a and b of Vab=1∠ 30º, if the base values are line-to-line base voltage of 1kV and three-phase base power of 100kW. Determine A) Line and phase voltages, line and phase currents of the load in delta, line and phase voltages of the star, line and phase currents of the star.B) Obtain separately the phasor diagram of the delta and star load with the values obtained in A), indicate on the scale that these are 1 p.u.=5cm for example.
