Question

A 100 kVA Generator has 10% reactance. Its short circuit kVA is:

• A. 100 kVA
• B. 500 kVA
• C. 1000 kVA
• D. 10000 kVA

Hint:

The short-circuit kVA of a generator is calculated by dividing the rated kVA by the percent reactance.

Answer 1

The Correct Option is C

The short-circuit kVA is calculated using the formula: \[ \text{Short circuit kVA} = \frac{\text{Rated kVA}}{\text{Percent reactance}} \] Given: - Rated kVA = 100 kVA, - Reactance = 10%. Substituting the values: \[ \text{Short circuit kVA} = \frac{100}{0.1} = 1000 \, \text{kVA} \] Thus, the short-circuit kVA of the generator is 1000 kVA, which corresponds to option (3).
