Dealing with a moisture-affected transformer is a critical issue that can lead to equipment malfunction, damage, or even fires. Here are the general steps to handle a moisture-affected transformer:

Disconnect Power: Firstly, ensure that the power supply to the transformer is cut off. This helps to avoid electrical accidents and personal safety risks.

Cease Usage: Immediately stop using the moisture-affected transformer to prevent further damage and hazards.

Isolation: Disconnect the moisture-affected transformer from the power source and other equipment, ensuring that no current flows through it.

Remove Moisture: Minor surface dampness can be gently wiped away using a dry cloth or paper towel. However, never use a hairdryer, heater, or any other heating device to remove moisture, as this might lead to a fire.

Drying Process: Place the transformer in a well-ventilated, dry area to facilitate the evaporation of moisture. Using a fan or specialized transformer drying equipment can expedite this process.

Insulation Check: After the transformer is completely dry, insulation testing is necessary to ensure that the insulation performance has not been compromised. This often requires specialized testing instruments.

Repair or Replacement: If moisture damage has affected the insulation properties of the transformer, or if issues persist after drying, seeking assistance from professional repair personnel is advisable. In some cases, damaged components or the entire transformer might need replacement.

Preventive Measures: To prevent similar situations in the future, consider implementing preventive measures such as maintaining a dry environment around the transformer and conducting regular insulation performance checks.

In summary, addressing a moisture-affected transformer requires caution and preferably the involvement of professional personnel for inspection, repair, and testing, ensuring safety and proper equipment operation.
