Can Transformer coils be replaced?

Issue:
Repair of Transformers

Product Line:
LV Transformers

Environment:
Applies to Low Voltage Transformers by SquareD/Schneider Electric

Cause:
Possible replacement of Transformer coils


Resolution:
Yes, but it is generally not practical from a cost standpoint to replace coils in Transformers smaller than 500 kVA. The coils cannot be removed without unstacking the steel laminated core, which is usually varnished and difficult to disassemble. Only personnel trained and authorized to repair Transformers should attempt to replace the coils.
