Question:

A 200-A: 5-A, 60-Hz current transformer has the following parameters as seen from the 200-A (primary) winding: X1 = 745μ Ω X’2 = 813μ Ω Xm = 307m Ω R1 = 136μ Ω R2 = 128μ Ω

a. Assuming a current of 200 A in the primary and that the secondary is short-circuited, find the magnitude and phase angle of the secondary current.

b. Repeat the calculation of part (a) if the CT is shorted through a 250μ Ω burden.
