What does N/A indicate regarding post-contingency thermal limits under normal conditions?

N/A, indicating "Not applicable," signifies that under normal conditions, the post-contingency thermal limits are not relevant or do not apply for a particular scenario. This can occur in situations where specific thermal ratings are either not required to be evaluated or where the system is not expected to experience any overloads that would affect thermal limits following a contingency event. Therefore, when thermal limits are marked as N/A, it suggests that the system is operating within a safe and stable range without the need for further evaluation for that specific condition. This classification is crucial for simplifying the analysis and focusing on applicable thermal limits, thereby optimizing system performance and reliability during typical operating conditions.
