(a) A resistance of 600 is selected as the base resistance in a (3 marks) circuit consists of three resistors. If Ri=12019, R2 = 120011, and R3 =1809, calculate the per-unit value of each resistance. (b) A power of, P = 25KW and a voltage of, E = 2500V are (2 marks) selected as the base power and base voltage of a power system respectively. Calculate the value of the base impedance, Z, and the base current, 1z. (c) A resistor has a per-unit value of 5.3. Given the base power is (3 marks) Py = 270KW, and the base voltage is E, =12700V, calculate the ohmic value (actual value) of the resistor. (d) A 6000 resistor carries a current of 604. Given the base value of voltage, E, = 5KV, the base value of power, P, = 500KW, the base value of current, 1, = 120.4, and the base value of resistor, Zn = 300, calculate the following: = i. The per-unit resistance. (2 marks) (2 marks) (2 marks) ii. The per-unit current. iii. The per-unit voltage across the resistor. iv. The per-unit power. v. The actual voltage across the resistor. vi. The actual power dissipated in the resistor. (2 marks) (2 marks) (2 marks)
