What should the operators monitor during a fault situation?

During a fault situation, operators should primarily focus on monitoring the current flow. This is crucial because a fault typically leads to an abnormal increase in current levels, which can signify short circuits or other issues within the electrical system. Accurately assessing current flow allows operators to quickly identify the severity of the fault, take necessary actions to isolate the faulted section, and implement appropriate protective measures to prevent further damage to equipment or the grid.

Current flow monitoring is essential for ensuring safety and reliability in electrical operations. It informs operators when to trigger circuit breakers or other protective devices to disconnect the affected area from the grid, thereby stabilizing the system and minimizing the risk of widespread outages or equipment failures.

While monitoring voltage levels, weather conditions, and power demand are also important aspects of overall grid management, they are not as immediately critical during a fault situation as current flow. The rapid changes in current during faults are the primary indicators that guides operators' actions.
