Question

For power-system fault studies, it is assumed that the system is operating under balanced steady-state conditions prior to the fault, and sequence networks are uncoupled before the fault occurs.

(a) True (b) False

Short answer

The correct answer is (a) True.

Step-by-step solution

Definition of power flow solution.

Power flow solutions are defined as any unusual situation of the system that involves the electrical failure of the equipment, such as, transformers, generators, busbar, and many more.

Determine for power-system fault studies.

In a power system fault analysis, it is considered that a system is in controlled environment under a balanced steady state condition before the fault happen.

Thus, the sequence components of power system are always disconnected as soon as the fault occur.

Therefore, the correct answer is (a) True.
