The results of a ‘Slip-Test’ for determining direct-axis (Xd) and quadrature-axis (Xq) reactances of a star-connected, salient-pole alternator are given below:
Phase values: Vmax = 108V; Vmin = 96V, Imax = 12A, Imin = 10A. Hence the two reactances will be 
  • a)
    Xd = 10.8 ohms and Xq = 8 ohms
  • b)
    Xd = 9 ohms and Xq = 9.6 ohms
  • c)
    Xd = 9.6 ohms and Xq = 9 ohms
  • d)
    Xd = 8 ohms and Xq = 10.8 ohms
Correct answer is option 'A'. Can you explain this answer?

Slip-Test for Determining Reactances of a Salient-Pole Alternator

Given Data:
Phase values: Vmax = 108V; Vmin = 96V, Imax = 12A, Imin = 10A

Calculations:
1. Calculation of Direct-Axis Reactance (Xd)
Xd = (3Vmin)/(2Imax) - (3Vmax)/(2Imin)
Xd = (3*96)/(2*12) - (3*108)/(2*10)
Xd = 10.8 ohms

2. Calculation of Quadrature-Axis Reactance (Xq)
Xq = (3Vmax)/(2Imax) - (3Vmin)/(2Imin)
Xq = (3*108)/(2*12) - (3*96)/(2*10)
Xq = 8 ohms

Final Answer:
The two reactances of the star-connected, salient-pole alternator are Xd = 10.8 ohms and Xq = 8 ohms. Therefore, option 'A' is the correct answer.
