Abstract
A transformer assembly for mounting a current transformer to an electrical apparatus. The generally toroidal current transformer senses electrical current in conductors of the electrical apparatus and has a housing. A mechanical lug for conductors of the electrical apparatus is mounted directly to the housing of the current transformer, within the central opening of the toroid. The mechanical lug has one or more conductor bores located within a main body of the mechanical lug for receiving respective conductor wires.
Claims15
A transformer assembly for an electrical apparatus, comprising:
- a current transformer for sensing electrical current in an electrical apparatus, the current transformer having a housing with an internal opening;
- and
- a mechanical lug mounted directly to the housing of the current transformer within the internal opening, the mechanical lug having a plurality of conductor bores located within a main body of the mechanical lug for receiving respective conductor wires, each of the conductor bores being located in part within the internal opening of the current transformer such that the conductor wires are receivable, respectively, in the conductor bores and within the internal opening, the mechanical lug having a mechanical lug apparatus for being attached to the electrical apparatus.
An electrical system comprising:
- an electrical apparatus;
- a mechanical lug physically and electrically mounted directly to the electrical apparatus, the mechanical lug including one or more conductor bores for receiving, respectively, one or more conductor wires, the conductor wires being attached to the mechanical lug via respective conductor fasteners;
- and
- a current transformer for sensing electrical current in the electrical apparatus, the current transformer being physically connected directly to the mechanical lug by having an internal opening in which the mechanical lug is received, each of the conductor bores being located in part within the internal opening of the current transformer such that the conductor wires are receivable, respectively, in the conductor bores and within the internal opening.
