  • Insulating support flange for current loop system
    Patent number: 9576723
    Abstract: The present invention relates generally to systems and methods for isolating a current loop conductor of a current loop system of a pre-charge circuit from a plurality of current transformers disposed around the current loop conductor. In particular, the embodiments described herein include an insulating support flange having a first tubular section, a second tubular section radially disposed around the first tubular section and connected to the first tubular section via a solid annular section extending radially outward from the first tubular section to a first end of the second tubular section, an annular base extending radially outward from a second end of the second tubular section, and a plurality of prongs extending axially from or near to an outer circumference of the annular base, wherein each of the prongs comprises an end face that is angled toward the second tubular section. The insulating support flanges are configured to mate with each other along an axial direction of the current loop conductor.
