A Case For Leak Repair

"If oil is leaking out, air and moisture can and often does get in. Moisture can migrate into transformers through several methods. One of the most common is through aged, leaking gaskets. Even though a transformer is at positive pressure, capillary action can draw moisture and air into the transformer, even when it is leaking oil in the opposite direction.

Rapid pressure changes attributed to cold weather operation and sudden removal from service (transformer switched out or de-energized) can increase the rate at which water is introduced into the transformer. Wherever oil is seen leaking from a transformer, those leaks should be repaired, as they are also areas where moisture and oxygen can infiltrate the unit"
