Yes, and it will be required to be sent back to the factory to untank the core and coil to evaluate for damage. I doubt if it's seizmic zone rating to this situation and certainly isn't braced for such a mishap.
If the core and coil can be reused I would estimate that it would set the project back at least a month. If the core and coil are damaged beyond repair the lead time on a new core and coil or a replacement transformer as probably over 6-8 months or more.

Do you really think it'll take that long? What if this transformer was in service, and destroyed by lightning? There must be a go around...
 
AS I told a facility technician one day as he dumped a data center by switching the wrong feeders. I hope you have a resume prepared.
 
Money does have a way to influence lead times. But have you checked the lead tomes for liquid filled transformers lately? If a factory?s production line were booked up for months and there is a need for a replacement core and coil people don't realize that an order that is put within an existing production schedule has to displace other orders. This causes the existing orders to miss their scheduled ship dates.

Extra money for overtime and the premium production space left to accommodate emergencies come at a premium price.
The are also transformer repair services available also the may be able to repair the transformer in a shorted time.
Then the question is if it was your transformer that you purchased brand new where would you like to have it evaluated, tested, rebuilt, and final production test performed? The manufacturer may have their engineering service group do the work but the fact remains if their os internal damage which I would think that there would be the factory would have to manufacture a new core and coil anyway.

As an application/sales engineer for a dry type power transformer manufacturing company it?s quite a challenge when you production schedule is filled up for 14 weeks and are already working overtime to maintain scheduled ship dates. There is just no way to squeeze anything in even with premium dollars without making other customers angry. Liquid filled transformer manufacturers compete with us in a way and we are well aware of their very long lead times. Where either type are acceptable in an application dries have a much-shorted lead-time but their inherent cost is considerably more.

Even the used transformer market is starting to dry up. Utility substation units are in the 24 month range, and industrial units (<10MVA) can easily exceed 12 months. I would probably have this unit factory inspected and put into service only until a "new" replacement could be delivered.

I dont know about that, I have 314 MV/LV transformers in stock today, both new and used, however they are all dry type, liquid filled you are out of luck.
