While the instantaneous electric power delivered by a single-phase generator under balanced steady-state conditions is a function of time having two components of a constant and a double-frequency sinusoid, i.e.. [single phase: p(t) = v max Imax (cos(0). – ) + cos(2wt +0,+8,] (1) the total instantaneous electric power delivered by a three-phase generator under balanced steady-state conditions is (three phase balance: Po(t) = 3VINI, cos(6 -- B). Which sentence in the following is correct about Pro(t): a) It is a constant b) It is time variant. 5. For a balanced-A load supplied by a balanced positive-sequence source, the line currents into the load are 3 times the A-load currents and lag by 30°. a) True b) False 6. A balanced A-load can be converted to an equivalent balanced-Y load by dividing the A-load impedance by b) 3 c) 1/3 Under balanced operating conditions, consider the 3-phase complex power delivered by the 3-phase source to the 3-phase load, let check the following expressions (real power): PsV3Vul cosøs.W (3) (reactive power) : 234 = V3V/sin svar total apparent power: Sy=V3V4/VA (5) complex apparent power] : $30 = Pse + jQ. (6) These expressions are: a) correct a) 3 b) wrong
