Abstract:
1. A current transformer comprising: (a) a first magnetically permeable core portion consisting of an elongate base having a cross-section, a first leg projecting substantially normal to said base proximate a first end of said base and terminating at a first leg end distal of said base and a second leg projecting substantially normal to said base proximate a second end of said base and terminating at a second leg end distal of said base and spaced apart from said first leg end; (b) a bobbin affixed to said base of said first core portion and including a portion substantially encircling said cross-section of said base; (c) a winding conductor including a portion wound on said bobbin and encircling said cross-section of said base; and (d) a second magnetically permeable core portion including a hinged connection with said first core portion enabling relative rotation of said first core portion and said second core portion about said hinged connection, relative rotation of said first core portion and said second core portion enabling conjoining of said first leg and said second leg and said second core portion, said first and said second core portions defining an aperture when said first leg and said second leg are proximate said second core portion, and relative rotation of said first core portion and said second core portion about said hinged connection enabling separation of said second leg and said second core portion.
