A synchronous machine with low value of short-circuit ratio has
A)lower stability limit
B)high stability limit
C)good speed regulation
D)good voltage regulation

Question

Quizplus · Accepted Answer

A synchronous machine with a low value of short-circuit ratio (SCR) has a lower stability limit. The short-circuit ratio is an indicator of the machine's ability to handle load changes without losing synchronism. A lower SCR means the machine has less capability to maintain stability under disturbances, leading to a lower stability limit.
