Transformer Testing And Maintenance

13.2KV cable fault and oil leak found during transformer testing and maintenance.

This was the first time the transformer was serviced and tested in the past 12 years.

We were able to replace the damaged cable and insulating barrier.

The leak was caused by a cracked bushing.  The customer has a scheduled shutdown planned for us to replace the damaged bushing and refill the transformer with oil.

These problems could have been found sooner (and possible avoided) with a routine maintenance and testing program.
