16. Moisture
If a transformer has been exposed to moisture such as
condensation or rain, the unit should be dried out prior to
re-energization. (refer to Dry-Out section)
Hot or warmed air, radiant heat or internal heat should be
directed through the windings. This should continue for 24
hours or until the evidence of condensation is no longer visible.
Transformers that have been exposed to flood conditions,
direct rain or sprinklers, may not be able to be dried out
appropriately. Consult the factory for further instructions.
If any of the above conditions are evident, the transformer
should be immediately removed from service. Corrective
measures should be taken in consultation with the
manufacturer.
After an evaluation has been completed it will be determined if
the transformer will be put back into service or returned to the
manufacturer for further testing.
