- Q3) A: A generator operating at 50 Hz delivers 1 pu power to an infinite bus through a transmission circuit in which resistance is ignored. A fault takes place reducing the maximum powe transferable to 0.5 pu whereas before the fault, this power was 2.0 pu and after the clearance of the fault, it is 1.5 pu. By the use of equal area criterion, determine the critical clearing angle.arrow_forward4. For the periodic signal shown in Fig. 4; a) Find the exponential Fourier Series for y(t). b) Use Parseval's Theorem to compute the total power contained in the 4th harmonic and all higher harmonics. 2+ y(t) + -2л -л 0 2л Зл 4л Fig. 4arrow_forward2. a) Find the Fourier transform of the signal shown in Fig. 2 and express it in its most compact form; b) Find the value of the energy spectral density at f=1/4. 0 -2 -1 -3.
