In almost all cases, upgrades can be fully achieved in the field without the need to return a transformer to a factory or workshop.

Bushings, cable boxes and tap selection equipment can also be upgraded to accommodate an increase in rating.

Simple upgrades can meet immediate need, defer major capital expenditure as well as give you time to assess your total needs.

The Wilson Engineering team can assess your transformer and determine the best course of action to achieve the most cost effective upgrade. Increases in nameplate rating of 20% to 25% are quite common with just the addition of fans.
