What is the purpose of maintaining a single time reference across a BALANCE area disturbance?

• A. To avoid time synchronization entirely.
• B. To require teams to log times independently.
• C. To coordinate response and maintain a consistent timing across teams and systems.
• D. To replace any need for logs or evidence.

Answer: (C)

Maintaining a single time reference during a BALANCE area disturbance is about coordinating response and ensuring consistent timing across teams and systems. In a disturbance, many sources—SCADA, protection devices, operator notes, and other measurements—produce time-stamped data. If each source uses its own clock, the sequence of events can become misordered, making it hard to coordinate actions or perform accurate post‑event analysis. A single authoritative time base (such as GPS-derived time) keeps all timestamps aligned, enabling correct event sequencing, data correlation, and effective restoration. It also supports evidence collection and root‑cause analysis. The goal isn’t to avoid time sync or force independent logging or to replace logs with timing alone—the logs still matter and need a common time reference to be meaningful.
