  4. Where can I find test data reports for GE transformers?
    GE offers two types of test data reports for dry-type transformers. They include: a) Certified Test Report and b) Typical Test Data (TTD) report.

    Certified Test Reports are created while a transformer is still in the factory, before it is shipped to the customer. Certified Test reports are unique to a specific transformer. A fee is charged for a Certified Test report and it must be ordered at the time the transformer is ordered. The Certified Test report is prepared by the GE Quality Manager and shipped with the transformer when it leaves the factory. It is easy to order a Certified Test Report. In Speedi, simply click on Accessories and select Certified Test Report. Speedi will add the Certified Test report to your bill of material and price it with the rest of the C&I components.

    Typical Test Data (TTD) reports are simply that... typical. They are not unique to a specific transformer but are representative for a catalog number. TTD's are provided free of charge and may be found in the GE Publication Library. Just search by catalog number and a TTD report will be displayed if it is available.
  5. Who can I call for technical assistance?
    For all technical questions regarding transformers, call GE Technical Support at 1-800-327-8155.
  6. Are lugs included with GE transformers?
    Lugs are factory installed and provided with all transformers 15kVA thru 225kVA
  7. What do I do if the transformer arrives at the customer site and the enclosure has been damaged during shipment?
    If it appears that the damage is minor and the enclosure has only sustained minor dents or scratches, top, side, front & rear replacement panels may be ordered free of charge from GE Resolve by calling 1-888-GE-RESOLVE or 1-888-437-3765. Open a service request and GE RESOLVE will ship new replacement panels to the customer.

    If the damage is significant and it is possible that the internal core and coil assembly has sustained damage, the transformer should not be used and must be replaced. The correct procedure is for the customer to file a claim with the transportation company and re-order a new transformer from GE.
