Normal Switching Operation Procedure

The first step in the normal operation of a switching process involves proper communication and preparation. Here's how it should be carried out:

1. The management team must inform the operation group of the specific area affected by the power shutdown and re-energization at least two days in advance. This includes details about transformer operations, such as which ones will be turned off or activated.

2. Upon receiving the notification, the operation team is expected to complete the following tasks within one day:

(1) Immediately contact the electrical professionals to arrive on-site and assess whether the load distribution is feasible.

(2) If the situation is not feasible (i.e., does not meet safety standards), report this immediately and provide clear reasons for the non-compliance.

(3) If the plan is feasible, clarify the time and scope of the power outage and re-energization. Once the operation table is completed, it must be reviewed and approved by the relevant leaders before being officially communicated to the management office in writing.

3. The management office will post the "Power Failure Notice" one day prior to the scheduled operation.

4. Before the actual switch operation, the personnel should prepare accordingly. For example, elevators should be lowered to the ground floor, and if necessary, the generator’s switch should be placed in the off position.

5. Under the supervision of a guardian, the operator should execute the "Power Failure Notice" as instructed.

6. After completing the switch operation, the operator must check the elevator’s functionality and ensure that the generator’s switch is set to the automatic position.

7. All activities and actions taken during the process must be thoroughly documented.

Emergency Barge Operation Procedure

1. In case of an emergency, such as detecting smoke, short circuits, or a major incident like a fire in the power distribution room, the operating staff has the authority to immediately perform a partial or full power shutdown. They should quickly disconnect the low-voltage power distribution cabinet or the high-voltage switch in the high-voltage cabinet.

2. As soon as the power is cut off, the management office and maintenance personnel must be notified immediately. Upon arrival, the maintenance team will investigate the cause of the incident and restore power gradually once the issue is identified. Damaged components should be repaired promptly, and normal power supply should be restored as soon as possible. At the same time, the fire center should use the broadcast system to explain the reason for the power outage to the residents.

3. All incidents must be recorded thoroughly. In the case of major emergencies, the incident should be reported immediately to the superior supervisor for further action.

This detailed procedure ensures safety, compliance, and efficient handling of both routine and emergency power operations.
