What must be done if you find a transformer door or cover is damaged?

When a transformer door or cover is damaged, it is essential to prioritize safety and equipment integrity. The correct action is to replace the damaged door or cover before turning on the power to the transformer. This is critical because a damaged door may compromise the safety features of the transformer, allowing for potential exposure to electrical hazards, moisture ingress, or foreign objects that could affect its operation.

Replacing the door or cover ensures that the transformer operates as designed, protecting both personnel and equipment from risks associated with electrical faults or failures. This proactive approach adheres to safety regulations and best practices in electrical work, helping to prevent accidents and maintain the reliability of the electrical system.

In contrast, delaying the replacement until after issues arise or ignoring the damage can lead to more severe consequences, such as equipment failure or safety incidents. Repairs made after hours do not address the immediate risk and may still leave the equipment vulnerable during that time. Thus, acting promptly by replacing the damaged component before re-energizing the transformer aligns with prudent electrical safety protocols.
