What is a significant risk during the restoration phase of the electrical grid?

• A. Improper communication between system operators
• B. Automatic reclosing of circuits when energized
• C. Inadequate training for newly hired operators
• D. Unforeseen natural disasters

Answer: (B)

During the restoration phase of the electrical grid, a significant risk is the automatic reclosing of circuits when energized. This process can lead to dangerous conditions because if a line is reenergized and there is still a fault present, it can result in equipment damage, further outages, or pose risks to personnel engaged in restoration efforts. When the grid is in a compromised state, restoring power must be done cautiously, taking into account existing faults and ensuring that all safety protocols are observed. Proper management and supervision during this phase are critical to prevent the inadvertent energization of faulty lines that could harm equipment and personnel. In contrast, while improper communication, inadequate training, and unforeseen natural disasters are certainly concerns during grid operations, they do not encompass the immediate risks pertaining to the specific mechanics of restoration. Automatic reclosing presents a direct and technical challenge that can create immediate grid instability, making it a key focus in the restoration phase.
