Transformer Installation

When purchasing a new transformer it will have to be received, assembled, vacuum-filled (if not shipped with oil) and commission tested prior to energization or storage.

SWE’s Substation Service Division is the logical choice to contract for this service. Many manufacturers offer this service but it is in the owner’s best interest to subcontract this service so as to insure an impartial assessment of the condition of the new transformer prior to acceptance.

SWE’s Substation Service Division has assembled transformers from 5 mVA to 500 mVA. Furnace transformers, Rectifiers, Rectiformers and GSU’s built by manufacturers from all over the world are just a few of the units serviced by SWE.

• Receiving of the unit from the Hauling Company
• Pre-offloading SFRA, Core Ground and Dewpoint testing
• Impact Recorder analysis
• Internal inspection for core movement and other shipping damage

• Inspection of accessories to be installed

• Dewpoint testing prior to vacuum-filling
