Q2. Consider the single-phase transformer circuit shown below. Transformer ratings and reactances are: Transformer A : 200 kVA, 250/ 750 V, X- 0.10 p.u. Transformer B : 100 kVA, 900/300 V , X= 0.15 p.u. The transmission line can be represented as a series impedance Zine = 0.4 +j 0.6 N. Choose a base of 200 kVA, 250 V in the voltage source ( V. ) circuit. (a) Draw the impedance diagram for this circuit, with all impedances in per unit. (b) Find the load voltage in per unit and in volts when the source voltage is V.-120° pu. (c) Find the transmission line current (IL.) in amperes. transmission line (Zi-0.4 + j0.6 2) B 4-0.5+ j0.2 2 0000 Leeee
