b. two 1-phase furnaces I and II are supplied at 80V by means of a Scott-connected transfor combination from a 3-phase, 6600V system) The voltage of furnace 1 is leading. Calculate line currents on the 3-phase side when the furnaces take 500kW and 800kW respectively (furnace 1) 0.707 power factor and (fuma II) at unity power factor. Draw the correspond vector diagrams.

A three-phase alternator generating unbalanced voltages is connected to an unbalanced load through a 3-phase transmission line as shown in figure. The neutral of the alternator and the star point of the load are solidly grounded. The phase voltages of the alternator are Ea = 1020º, Eb = 102-90°, Ec = 10/120⁰ E E E The positive sequence component of the load current is (A) 1.3102-107⁰ A (B) 0.3322-120° A (C) 0.9962-120º A (D) 3.5104-81⁰ A +) + j1.002 0000 j1.002 0000 j1.0Ω vovo j1.0Ω 0000 j2.002 voor j3.002 oooo

Discussion:- Does K.C.L. & K.V.L depend on the relationship between current and voltage in a resistor, Explain? 2- Explain why two voltage sources of different voltage rating cannot be connected in parallel. What is the corresponding statement for current sources?- Show that for a circuit with (n) nodes it is sufficient to write the K.C.L. for (n-1) nodes and that the K.C.L. for Nth node is not independent (support your answer with an auou
