When is the V relay in danger state activated?

When is the V relay in danger state activated?

• A. When TP energized and DV in cycle check
• B. When H energized or T de-energized
• C. When HV de-energized
• D. When HV ahead and HV in advanced

Answer: (C)

The activation of the V relay into a danger state occurs when the HV, or high voltage, is de-energized. This indicates that the system is experiencing a significant loss of power or that the voltage critical for operation is no longer present. The danger state ensures that appropriate safety protocols are engaged to protect both the equipment and personnel from potential hazards that may arise due to inadequate voltage levels. When HV de-energized, it signifies a critical condition that typically requires immediate response to prevent operational failures or unsafe scenarios. By categorizing this state as a danger state, the system can initiate protective measures, such as isolating certain components, alerting operators, or triggering alarms, to manage and mitigate risks effectively. This understanding of HV's role in the system contributes to line control practices, as operators learn to recognize the importance of voltage states and how they can impact overall system safety and reliability.
