What steps ensure safe recovery and re-energization after completing a repair?

• A. Inspect the equipment and confirm ground continuity.
• B. Verify protection settings and re-energize remotely.
• C. Coordinate with the control room to energize.
• D. Inspect the equipment, perform a controlled re-energization, verify protection settings, and notify operations once restored.

Answer: (D)

Safe recovery after a repair hinges on a controlled re-energization sequence, thorough inspection, verification of protection settings, and clear communication with operations. Start by inspecting the equipment to confirm it’s properly isolated, all devices are in the correct position, and there are no hazards or left‑behind tools or debris. This step ensures there’s no hidden fault or risk as you bring the circuit back online. Next, perform a controlled re-energization. Re-energize in a planned, stepwise manner rather than jumping back to full voltage, which helps prevent arc flash, inrush, or unintended energization of adjacent equipment. This controlled approach also allows you to confirm each stage is progressing safely. Then verify protection settings. Checking relays, breakers, and other protective devices ensures they will respond correctly if a fault occurs after restoration, safeguarding both personnel and equipment. Finally, notify operations once restored. Communicating status to the control room and other relevant teams keeps everyone informed, coordinates system status, and prevents conflicting actions. The other options omit one or more of these essential steps: they may skip the controlled re-energization, skip verification of protection settings, omit the inspection, or neglect notifying operations, all of which are necessary for a safe and reliable re-energization.
