Question 2

A major transmission line trips due to a fault and automatic reclosing fails. What is the operator's next step?

Accepted Answer

Attempt a manual reclose after verifying the line is de-energized

Accepted Answer

A portion of the grid operating isolated from the main interconnection

Answer

Islanding occurs when a section of the power system becomes electrically isolated and continues to operate independently from the bulk grid.

Question 4

Under NERC EOP standards, when must a Transmission Operator notify its Reliability Coordinator of an emergency?

Accepted Answer

As soon as the operator becomes aware of a condition that could impact reliability

Answer

NERC EOP standards require immediate notification to the Reliability Coordinator as soon as a reliability-threatening condition is identified.
