Abstract: A modular toroidal transformer core assembly, including a plurality of interconnected semicircular core segments defining an annular core. Each respective semicircular core segment further includes a plurality of curved steel layers defining a semicircular core segment having a first end and a second end with a plurality of fingers extending from each end and a plurality of gaps extending from each end, wherein each respective gap lies between and is defined between two respective fingers. Each respective finger defines a predetermined number of layers. An aperture extends through each end of the respective semicircular core segments, with a fastener extending through each respective aperture to hold each respective semicircular core segment together. Each respective semicircular core segments is interlockingly engaged with another respective semicircular core segment to define the annular core.

Abstract: A modular toroidal transformer core cap system, including a plurality of cap segments, wherein each respective cap segment further includes first and second spaced elongated wall members, first and second connector members connected to the respective first and second elongated wall members, and a generally flat panel member connected to and extending between the first and second elongated wall members. The first and second wall members are disposed at a predetermined angle relative one another and the first and second elongated wall members and the panel member are electrically nonconducting. An integral number of cap segments may be joined together to define an annular core cap.
