What should be done when the actual voltage drops below the load dump low voltage limit?

When the actual voltage drops below the load dump low voltage limit, it is crucial to take immediate action to raise the voltage. This is because a voltage drop can lead to instability in the power system and may cause outages or damage to equipment. By implementing actions to raise the voltage promptly, operators can help restore stability and ensure that the system continues to function effectively.

Raising the voltage could involve a variety of strategies, such as adjusting generator output, utilizing reactive power support, or activating voltage regulation systems. This proactive approach helps to prevent further degradation of the system and protects both the infrastructure and connected loads from adverse effects associated with low voltage conditions.

In contrast, waiting for power restoration or disconnecting from the grid does not directly address the problem at hand. Reducing load may offer a temporary fix but doesn’t solve the underlying issue of insufficient voltage. Only by immediately taking corrective actions can the integrity of the power system be maintained.
