Critical clearing angle.
The critical clearing angle , is the maximum allowable change in the power angle δ before clearing the fault, without loss of synchronism.
The time corresponding to this angle is called critical clearing time, .It can be defined as the maximum time delay that can be allowed to clear a fault without loss of synchronism.

(iii).Use of high speed excitation systems
(iv). Use of high speed reclosing breakers
