For a fault in a power system, the term critical clearing time is related to,
- A. Transient stability limit
- B. Reactive power limit
- C. Short circuit current limit
- D. Steady state stability limit
Answer: A. Transient stability limit
Explanation: Critical clearing time is the maximum allowable time duration for which a fault can remain on the system before circuit breakers clear it without loss of synchronism, defining the transient stability limit.
