Abstract
A transformer apparatus that may be applied as a distribution circuit adaptor (DCA) inserted into a branch supply circuit to reduce losses in a power distribution network. More particularly, implementations of the present disclosure provide a high-efficiency 2-phase dry type transformer apparatus with a removable core, as well as integrated instrumentation and thermal self-management.
Claims11
A method of providing a transformer apparatus, the method comprising:
- providing first and second coil banks spaced apart from each other, each of the first and second coil banks includes at least one coil;
- providing at least one instrumentation transformer;
- casting a first encasement around the first and second coil banks and the at least one instrument transformer, wherein the first encasement includes first and second passages therein spaced apart from each other, each of the first and second passages extends between a top and a bottom of the first encasement within a respective one of the first and second coil banks;
- positioning a first core leg within the first passage of the first encasement, the first core leg includes an upper end and a lower end opposite the upper end;
- positioning a second core leg within the second passage of the first encasement, the second core leg includes an upper end and a lower end opposite the upper end;
- coupling a top core bridge to each of the respective upper ends of the first and second core legs;
- and
- coupling a bottom core bridge to each of the respective lower ends of the first and second core legs.
