What kind of voltage range should be maintained during the system restoration phase?

Explanation:
During the system restoration phase, it is essential to maintain the voltage within a range of 90% to 110% of the nominal voltage. This tolerance is crucial because it ensures the stability and reliability of the power system while restoration activities are taking place. Maintaining voltage within this range helps prevent damage to equipment and minimizes the risk of overloads or voltage collapse. The flexibility of 90% to 110% allows operators to adjust to various system conditions and loads that may be fluctuating during the restoration process. This range is aligned with industry standards, which prioritize safety and performance while managing the complexities involved in restoring power. In contrast to the other options, the specified range in the correct answer effectively balances system performance and equipment safety, making it the preferred approach during restoration.
