Abstract
An arrangement for securing a current transformer to an electric utility meter housing. The arrangement includes a utility meter base plate which forms a portion of the electric utility meter housing. The utility meter base plate includes (i) a first central axis and (ii) a transformer receptacle defined therein. The transformer receptacle has an opening and a first retention surface. The arrangement also has a current transformer assembly including (i) the current transformer and (ii) a wall member affixed to the current transformer. The wall member defines an annular channel having a second central axis, and the current transformer is positioned within the annular channel. The transformer assembly also includes a tab having a second retention surface. The tab extends from the wall member. The current transformer assembly is secured to the utility meter base plate, such that the first central axis is substantially parallel with the second central axis, when the tab is disposed within the transformer receptacle so that the first retention surface engages the second retention surface. An associated method of securing a current transformer to an electric utility meter is also disclosed.

17. A method of securing a current transformer to an electric utility meter housing having a base plate, said base plate having a transformer receptacle defined therein, said transformer receptacle including an opening and a first retention surface, said current transformer disposed within a current transformer assembly that includes a wall member affixed to said current transformer and a tab extending from said wall member, said tab including a second retention surface, the method comprising:
-
positioning said current transformer assembly such that said tab is disposed proximate said opening; effecting movement of said current transformer assembly such that said tab traverses said opening; and causing elastic deformation of at least one of said tab and said transformer receptacle to facilitate traversal of said opening by said tab so as to position said tab in said transformer receptacle such that (i) said first retention surface engages said second retention surface and (ii) said current transformer assembly is secured to said utility meter base plate.
