Following data are obtained by slip test on a salient pole machine:
$$I_{dmax} = 10 A$$ $$I_{dmin} = 6.5 A$$
$$V_{dmax} = 30 V$$ $$V_{dmin} = 25 V$$
What is the direct axis reactance $$‘X_d’$$ and quadrature axis reactance $$‘X_q’$$?

A

$$X_d = 3 Ω, X_q = 3.86 Ω$$

B

$$X_d = 4.61 Ω, X_q = 2.5 Ω$$

C

$$X_d = 3 Ω, X_q = 2.5 Ω$$

D

$$X_d = 4.61 Ω, X_q = 3.86 Ω$$
