In relation to voltage limits during pre-contingency, what is the maximum time allowed for high voltage situations?

During pre-contingency, a temporary overvoltage is allowed to persist for a limited window so operators have time to implement the planned corrective actions without immediately violating limits. The maximum time for a high voltage condition is fifteen minutes. This duration strikes a balance: it provides enough room to re-dispatch generation, adjust voltage control devices (like tap changers or AVR settings), and carry out other corrective steps, while keeping exposure to overvoltage short enough to avoid equipment stress or protection issues. If the voltage remains high beyond this window, the pre-contingency plan requires actions to bring it back within limits.
