Q. Five alternators each rated 5 MVA, 13.2 kV with 25% of reactance on its own base are connected in parallel to a busbar. The short-circuit level in MVA at the busbar is .
Ans: 100
Solution:
Reactance of each alternator = 0.25 As all the five alternators are connected in parallel, the equivalent reactance
